For the data in Problem 10.22, compute the energy loss for gradual contractions with each of the cone angles listed in Figs. 10.10 and 10.11. Plot energy loss versus the cone angle.

Problem 10.22

Determine the energy loss for a sudden contraction from a 4-in Schedule 80 steel pipe to a 1½-in Schedule 80 pipe for a flow rate of 250 gal/min.
