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