Assume this is Schedule 40 pipe, C = 120. Use the
Hazen-Williams formula to calculate the friction loss
for the 1 ¼ in. pipe and the 1 ½ in. pipe.
For 1 ¼ in. pipe (ID = 1.38):
P friction loss = 4.52 x Q 1.85
c 1.85 x d 4.87
P friction loss = 4.52 x 100 1.85
120 1.85 x 1.38 4.87
P friction loss = 0.672 psi/ft
For 1 ½ in. pipe (ID = 1.61):
100 GPM is flowing
P friction loss = 4.52 x Q 1.85
through 100' of 1 1/4 in.
Sch. 40 pipe. How many
c 1.85 x d 4.87
feet of 1 1/2 in. pipe will
produce the same friction
P friction loss = 4.52 x 100 1.85
loss?
120 1.85 x 1.61 4.87
P friction loss = 0.317 psi/ft
Step #2: Determine the total friction loss for 100 gpm
flowing through 100 ft. of 1 ¼ in. Schedule 40 black
steel pipe: 100 ft. x 0.672 psi/ft = 67.2 psi
