A rectangular culvert 4 feet x 6 feet is running full and discharging 3,500 cfm. There is no friction loss. Find the velocity in fps. The culvert empties into a 10 ft wide culvert and the velocity reduces to 0.6 fps. How deep is the water level in the second culvert?
A 1kg ball is dropped from the top of a cliff and falls with a constant acceleration due to gravity. Assume that effects of air resistance can be ignored.
