Flow Rate, Velocity and Friction Loss (Water)
Friction loss state within the following tables is
based on pipe dimensional data using the Darcy-
Weisbach equation:
h
f
= f • L • V²
D 2
g
h = friction loss
L = pipe length
D = pipe ID
V = velocity (ft./sec.)
g = gravity constant (32.174ft./sec.²)
f = pipe friction factor
