A rectangular channel 6 m wide with a depth of flow of 3 m has a mean velocity of 1.5 m/s. The channel undergoes a smooth, gradual contraction to a width of 4.5 m. (a) Calculate the depth and velocity in the contracted section. (b) Calculate the net fluid force on the walls and floor of the contraction in the flow direction. In each case, identify any assumptions made.
