[sushmitarp]

What is your static pressure at the base of the tower? ________________________

What is the static pressure loss through the last head (A)? ________________________

What is your friction loss for each of the following?

Pipe A __________________________

Pipe B __________________________

Main Line __________________________

Service Line __________________________

Fittings __________________________
(Assume this friction loss is equal to 10% of the friction loss of all pipes)

Valve __________________________

Meter __________________________

Total friction loss from point of connection (P.O.C.) to Head A when valve is operating:
