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
2.6.1 Flow Rate, Velocity, and Friction Loss (Water)
Where:
h
f
= friction loss
L = pipe length
D = pipe ID
V = velocity (ft./sec.)
g = gravity constant (32.174ft./sec.²)
f = pipe friction factor
Flow Rate (gpm)
