1. Draw the specific energy diagram for the flow described in Problem 15.11, and use it to solve this problem.

Problem 15.11

A flow in a rectangular channel 1 m deep with a velocity of 0.3 m/s approaches a smooth channel rise of 0.3 m. What is the depth after the rise?

2. Draw the specific energy diagram for the flow described in Problem 15.12, and use it to solve this problem.

Problem 15.12

A flow in a 3 ft wide rectangular channel is 3 ft deep and has a flow rate of 0.2 ft³/s approaching a smooth drop of 2.5 in. What is the depth after the drop?
