A trapezoidal channel having a bed width of 7.0 ft and a side slope of 3: 2 is discharging 300
/s of water. If the specific energy is equal 5.7 ft, calculate the alternate depths and their corresponding slopes to satisfy these conditions. Take n = 0.025.

A rectangular channel 5 m wide carries a discharge of 25
/s. The observed velocity at a particular point in the channel is 2.5 m/s:

a. What is the specific energy of the flow at this point?

b. What are the alternate depths at this point?

c. What is the critical depth in the channel?
