discharge rate of water = 12 m^3/sec width of the rectangular channel = 3 meters   1. Given the depths of 30 centimeters, 1 meter, and 2 meters, what are the Froude number and flow type (supercritical, subcritical, critical)? 2. Determine the critical depth 3. Determine the alternate depth to the 30 cm depth and the specific energy for these conditions.

Water flows in a horizontal, rectangular channel initially 10 feet wide and 2 feet deep. The initial velocity is 6 ft/s. This flow encounters downstream a simultaneous downward step and constriction. No energy losses are associated with these changes in channel configuration. a. What is the specific discharge, q: i. Upstream (for w= 10 feet)? ii. Downstream (for w = 6 feet)? b. What specific energy, E, is associated with the flow as initially specified (at the upstream location)? c. What is the minimum energy needed to pass the full discharge at the downstream location? d. What is the height (Az) of the smallest downward step necessary for the upstream flow conditions to remain as specified?
