RESISTANCE OF VALVES AND FITTINGS TO FLOW OF FLUIDS

A simple way to account for the resistance offered to flow by valves and fittings is to add to the length of pipe in the line a length which will give a pressure drop equal to that which occurs in the valves and fittings in the line
Example: The dotted line shows that the resistance of a 6-inch Standard Elbow is equivalent to approximately 16 feet of 6-inch Standard Steel Pipe
Note: For sudden enlargements or sudden contractions, use the smaller diameter on the nominal pipe size scale

Thermal overload heaters in a starter provide protection for the motor and should be selected on the basis of motor current obtained from the motor nameplate and the type of starter enclosure.
For three phase power 3 heater elements are recommended for maximum protection. If fusetrons are used instead of the instantaneous type fuse the size should be selected based on motor current similarly to thermal overload elements.

USEFUL PUMP DATA

EFFECT OF SMALL CHANGES OF PUMP SPEED

1. The capacity varies directly as the speed
2. The head varies as the square of the speed
3. The brake horsepower varies as the cube of the speed

EFFECT OF SMALL CHANGES OF IMPELLER DIAMETER

1. The capacity varies directly as the diameter
2. The head varies as the square of the diameter
3. The brake horsepower varies as the cube of the diameter

EFFECT OF SPECIFIC GRAVITY
Brake horsepower varies directly with specific gravity If the liquid has a specific gravity other than water (1 0) multiply the brake horsepower for water by the specific gravity of the liquid to be handled A centrifugal pump will always develop the same head in feet no matter what the specific gravity of the liquid pumped However, the pressure (in pounds per square inch) will be increased or decreased in direct proportion to the specific gravity

EFFECT OF VISCOSITY
Viscous liquids tend to reduce pump capacity, head and efficiency and to increase pump brake horsepower and increase pipe line friction See page 11 for correction factors
EFFECT OF ALTITUDE
Suction lift data are based on values at sea level Therefore, above sea level the total suction lift must be reduced
EFFECT OF HOT LIQUIDS
Hot liquids vaporize at higher absolute pressures than cold liquids, therefore the suction lift must be reduced when handling hot liquids When handling liquids with a high vapor pressure or at high temperatures the liquid must flow to the pump suction under pressure

NOTE 2 If no air charger is employed, increase tonk size by approximately 50%
NOTE 3 Tank capacity should be increased 25% for elevations above 5000 feet

WATER REQUIRED PER MINUTE TO FEED BOILERS

One Boiler Horse-Power equals 34 5 lbs of water evaporated per hour from and at 212 degrees Fahrenheit
One Gallon of Water weighs 8 34 lbs at 60 degrees Fahrenheit
Boiler H P times 069 Gallons per minute Feed Water required

In selecting Boiler Feed pumps, the fact that boilers are often run 200 and 300 percent of rating should be taken into consideration The above figures are of the actual Boiler Horse-Power developed

BELT DRIVE SELECTION OF “V” BELT SECTION AND SHEAVE

BELT SPEED
For satisfactory operation and belt life, the pulleys should be as large as possible without exceeding a belt speed of 5000 feet per minute Belt Speed = S = 26D x RPM = Feet per minute as may be determined from the following table
The pulley should not be greater than 5 ⁄2’’ for 3500 RPM
Example: If the pulley diameter (D) is 6”, and its speed is 1750 rpm, then the belt speed = S = 26 x 6 x 1750 = 2740 feet per minute
The following table shows speed RPM which a pulley of diameter (D) may be run for a belt speed of 5000 feet per minute

ESTIMATION OF 50 CYCLE PERFORMANCE

FIG 2
The above example is based on the published curves for BERKELEY Model 1 1⁄2YPH which indicate a speed of 1760 RPM for 60 cycles To estimate the performance of this pump using 50 cycle current, proceed as follows:
Step 1 Select points on the Head/Capacity curve (Fig I) in the approximate area in which you expect to work
Label them as indicated Pick corresponding points on the BHP and Efficiency curves directly below the above points
Step 2 Construct a table (Fig 2 ) as shown above and insert the 60 cycle values for Capacity, Head and Horsepower
Step 3 Calculate the new values for 50 cycles
Step 4 Plot the new Head/Capacity and Horsepower points and draw the performance curves
Step 5 Determine the new efficiency curve by moving the points on the 60 cycle curve horizontally to the left to the new capacity values OR calculate the corresponding efficiencies by means of the formula and plot the new Efficiency Curve If the area of concern is known quite closely it is frequently only necessary to select one set of points and to make the necessary calculations Plot the new points and then draw small segments of the new performance curves parallel to the 60 cycle ones

ESTIMATION OF PERFORMANCE With Trimmed Impeller

FIG 4

The above example is based on the published curves for BERKELEY Model 1 1⁄2 YPH (1760 RPM) which indicates an impeller diameter of 8 1⁄4” To estimate the performance of this pump using an impeller of 6 7/8” diameter proceed as follows:
Step 1 Select points on the Head/Capacity curve (Fig 3) in the approximate area in which you expect to work Label them as indicated Pick corresponding points on the Horsepower and Efficiency curves directly below the above points
Step 2 Construct a table (Fig 4) as shown above and insert the 8 1⁄4” diameter values for Capacity, Head and Horsepower
Step 3 Calculate the new values for 6 7/8” diameter
Step 4 Plot the new Head/Capacity and Horsepower points and draw the performance curves
Step 5 Determine the new efficiency curve by moving the points on the 81⁄4” diameter curve horizontally to the left to the new capacity values OR calculate the corresponding efficiencies by means of the formula and plot the new Efficiency curve If the area of concern is known quite closely it is frequently only necessary to select one set of points and to make the necessary calculations Plot the new points and then draw small segments of the new performance curves parallel to the 8 14” diameter ones

SUCTION LIMITS – TDSL

Suction limit correction for altitude and temperature
Several factors must be controlled for satisfactory performance of a centrifugal pump One of these is arrival of the water at the inlet to the pump in a condition that is within the suction ability of the pump Operation with on excessive Total Dynamic Suction Lift DEMAND (TDSL Demand) for the supply piping system will usually reduce the capacity and efficiency of the pump, and may lead to serious trouble through vibration and cavitation To ovoid this, the TDSL DEMAND for the suction piping system may be calculated, and compared against the TDSL ABILITY of the pump, which is shown as “TDSL” on the pump performance curve

TO CALCULATE TDSL DEMAND FOR SUCTION PIPING SYSTEM

1. Measure the vertical lift (HL in feet) from the surface of the water source to the center line of the impeller eye
2. Calculate the EQUIVALENT LENGTH of the suction piping system Include pipe, fittings, strainer, etc Refer to Table of Equivalent Lengths for Fittings (see Engineering 9020)
3. Calculate the Friction Loss (H L in feet) at the required GPM flow rate through the equivalent length of the size and type of pipe used (see Engineering 9020) 4 Determine the Velocity Head (H in feet) shown in the Pipe Friction Table, at the required GPM, for the pipe size for which the pump inlet is machined (Note: ALWAYS use the Velocity Head for the pump inlet size, even though larger pipe is used for the main run and reduced to pump inlet size at the pump )
4.  Add the three values found above: HE+ HL+ HVV= TDSL DEMAND for the suction piping system

TO MEASURE TDSL DEMAND FOR THE SUCTION PIPING SYSTEM FOR AN EXISTING PUMP

1. Install a vacuum gauge in the suction pipe about one pipe diameter upstream from the pump inlet opening, preferably into a piece of pipe the same size as the pump inlet
2. Operate the pump at the required flow rate Read the vacuum  gauge
3.  Multiply the vacuum gauge reading, in inches of mercury, times 1 13, to convert to feet of water This is the TDSL DEMAND for the suction piping system at the observed flow rate (Note: If the vacuum gauge must be installed in a pipe that is larger than the pump inlet opening, compute the difference between the velocity heads for the different pipe sizes, and ADD the difference to the vacuum gauge reading to obtain the TDSL DEMAND )

COMPARISON OF TDSL DEMAND AGAINST TDSL ABILITY OF PUMP

1. Obtain the TDSL at the required GPM from the pump performance curve This is the TDSL ABILITY of the pump when pumping WATER, at 70˚F or less, at Sea Level For higher water temperatures, or higher altitude, find the correction in the Table below, and SUBTRACT it from the pump TDSL ABILITY
2. Compare the TDSL DEMAND (either calculated or measured) against the corrected TDSL ABILITY
3. If the TDSL DEMAND is LESS than the TDSL ABILITY, the suction condition is acceptable
4. If the TDSL DEMAND is EQUAL TO or GREATER THAN the TDSL ABILITY, cavitation can be expected

SYSTEM CORRECTIONS If the TDSL DEMAND exceeds the adjusted TDSL ABILITY of the pump, it may be possible to reduce the TDSL DEMAND by lowering the pump to reduce the vertical lift, or by using a larger size pipe to reduce the Friction Loss If these adjustments ore still not adequate, select a different pump with a greater TDSL ABILITY

Above values represent horsepower constant of the meter They are determined by multiplying Kh value (stamped on nameplate of meter) by 0 0804 For meters not listed above, horsepower constants can be calculated from Kh value
EXAMPLE: G E Meter (two element) Type V2-A 240V 50 Amp
Meter Disk RPM = 15
H P Demand = 1 9303 x 15 = 28 95 HP

COMPUTING HP FROM RPM OF WATTHOUR METER DISC

An accurate method of measuring power consumption is of general interest to the owner or operator of electrically driven equipment including pumps The watthour meter is used to measure the power consumed The meter is usually mounted on the power pole or wall of pump housing adjacent to the motor control equipment
Current and/or potential transformers are required for larger units to reduce line current and voltage to the capacity of the watthour meter When computing the horsepower consumption by this method, it is important that the horsepower consumption obtained from the watthour meter be multiplied by the ratio of both current and potential transformers to obtain the correct power consumption of the motor
CURRENT TRANSFORMERS (C T s) Basic rating of all standard C T s used in metering is 5 amps secondary and, in general, no smaller than 200 amps primary (there are still in use C T s of the following ratios: 100:5 and 150:5 – these ratios are very seldom supplied on new installations) C T s most commonly used and in current issue are called 200, 400, 600 and 800 amp C T s with the 5 being understood

POTENTIAL TRANSFORMERS (P T s – for metering purposes )
100-120 volt and 200-240 volt systems do not require P T s
Most 400 to 480 volt systems now metered without P T s
There are, however, some 400 to 480 volt systems using 4:1
P T ‘s with 120 volt meters
Most 2300 volt systems use 20:1 P T s with 120 volt meters, 4000 volt WYE (or Star) – 2300 volt Delta
7200 volt Delta or 12,000 volt WYE (or Star) use a 60:1 P T s
HORSEPOWER CONSTANTS OF THE METER All meters now installed have the Kh value stamped on the nameplate This Kh value represents the number of watt hours passed through the meter while the disc makes one revolution The Kh value multiplied by 60/746, or 0 0804, gives the horsepower constant of the meter The horsepower constant of the meter multiplied by the RPM of the disc gives the horsepower input to motor .
Where Kh is not available, use the chart on Page 29 to obtain the proper horsepower constant For example: Westinghouse 2 element meter, type DA, 480 volt, 50 ampere
Horsepower constant = 3 861
Horsepower input = 3 861 x meter disc RPM
USE OF CURRENT AND POTENTIAL TRANSFORMERS Where current and potential transformers are used, the horsepower constant of the meter must be multiplied by a factor M to obtain the true horsepower constant Example: Assume a G E Meter type V-62 series, 2 element,120 volt, 5 amp, Kh amp, =
Meter disc makes 5 revolutions in 2 min 38 seconds (158 seconds)
Current transformer rated 200:5
Potential transformer rated 480:120
Basic horsepower constant:
(1) (from chart) 0 1930
(2) (by computation) using True horsepower constant 0 1930 X 160 = 30 88
RPM of disc = 1 9
Horsepower 30 88 X 1 9 = 58 7
