Using the Powell equation, what quantity of liquid will flow in a smooth rectangular channel 2 ft wide, on a slope of 0.010, if the depth is 1.00 ft? (Use v = 0.00042 ft 2 /sec.) Water flows in a rectangular concrete open channel that is 12.0 m wide at a depth of 2.5 m. The channel slope is 0.0028. Find the water velocity and flow rate.
