A river has a cross section that is approximately a rectangle with 10 ft deep and 50 ft wide. The average velocity is 1 ft/s. How many gallons per minute pass a given point? What is the average velocity at a point downstream, where the channel shape has changed to 7 ft in depth and 150 ft in wide? Given 1 ft3 = 7.48 gallons. Cross-sectional area of the river: 10 ft 50 ft 7 ft 150 ft
