Problem 1.

Estimate the discharge of water (T =10$^o$C) that flows 1.5 m deep in a long rectangular concrete channel that is 3 m wide and is on a slope of 0.001.

Problem 2.

Water flows at a rate of 8$\frac{m^3}{s}$ in a rectangular channel 2 m wide.

  1. What is the Froude number for depths of 30 cm, 1.0 m, and 2.0 m?
  2. Classify the flow (sub-, super-, or critical) type for these three depths.

Problem 3.

A long rectangular channel that is 8 m wide and has a mild slope ends in a free outfall.

If the water depth at the brink is 0.55 m, what is the discharge ($\frac{m^3}{sec}$)in the channel?
