100 GPM is flowing through 100' of 1 1/4 in. Sch. 40 pipe.
How many feet of 1 1/2 in. pipe will produce the same
friction loss? - Answer-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
