Theoretical Calculations Flashcards
1
Q
GPM Calculation
A
GPM = 29.7 x d^2 x Square Root of NP
2
Q
Friction Loss Calcuation
A
FL = C x Q^2 x L
Q = GPM/100
L = Length/100
3
Q
Elevation Pressure Loss
A
EP = 5 psi/10 feet
EP = 0.5 x Height
4
Q
Pump Discharge Pressure
A
PDP = NP + TPL
5
Q
Fiction Loss Coefficients
A
1 3/4” = 15.5
2 1/2” = 2
3” w/ 2 1/2” Couplings = 0.8
