1. 8.6 Gallon per minute buiding demand, predominatly Flush Tank.
2. 55.0 Low pressure at the Main in Street.
3. 3.5 Lb loss from a 8.0 ft difference in elevation from Main in Street to the Water Meter.
4a.~ Lb loss from a 80.0 ft 3/4" Copper Tube Type L ASTM B88 water service from the Main in Street to the Water Meter.
Pressure loss detemined using a C value of 130, inside diameter of .785 and a velocity of 5.7 ft per sec.
4b.~ No 2nd part water lateral.
5. 1.1 Lb loss from a 3/4in Meter
6. 42.6 Lbs of pressure available at the Water Meter. This value is entered in (B) below.
The (A) value listed below is determined by using the following formula, then rounding the result up.
A = B-(C+D+E) x 100
F
A. ~ Pressure available for uniform loss (psi/I 00 feet of pipe).
B. ~ Lbs of pressure available at the Water Meter.
C. ~ Pressure needed at the controlling fixture. PB T/S valve
D. --.l.d Lb loss resulting from a 3.0 ft difference in elevation from the Water Meter to the controlling fixture.
E. .0 Lb pressure loss due to a no pressure loss devices serving the controlling fixture.
F. 30.0 Ft Developed length from the 20.0 ft actual length of piping from the Water Meter to the controlling fixture.

WATER CALCULATION WORKSHEET
INFORMATION REQUIRED TO CALCULATE WATER SERVICE SIZE
1. Demand of building In gallons per minutes.
2. Difference in elevation from main or external pressure tank to building control valve.
3. Size of water meter {when meter is required 5/8" ---' 3/4" L. 1" --.I. 1/2"---,-
4. Developed length from main or external pressure tank to building control valve.
5. Low pressure at main in street or external pressure tank.
