Question:

An open tank L ft long as shown below travels to the right at a velocity v_cfps. A jet of area A_jexhausts fluid of density r at a velocity v_jfps relative to the car. The tank car, at the same time, collects fluids from an overhead sprinkler that directs fluid downward with velocity v_s. Assuming that the sprinkler flow is uniform over the car area, A_c, determine the net force of the fluid on the tank car.
