Two streams merge to form a river. One stream has a width of 8.4 m, depth of 3.5 m, and current speed of 2.1 m/s. The other stream is 6.4 m wide and 3.1 m deep, and flows at 2.5 m/s. If the river has width 10.5 m and speed 2.8 m/s, what is its depth? Clearly explain why the Volume Flow rate R, (the volume of fluid per second that passes a point in a flow), is equal to the cross sectional area times the velocity. R = Av
