Q

What is the pump discharge formula?

A

PDP = NP + FL + AP +/- EL

Q

What is the friction loss formula?

A

FL + GPM X HS / 10 and then -10
per 100 ft (Handline)

Q x (Q-1) / HS = MS
Q= GPM/100

What is static pressure?

A

Intake pressure of water when no water is flowing

Q

What is residual pressure?

A

intake pressure of water after flowing water out of pump
