Question 5: A water jet of velocity V; impinges normal to a flat plate which moves to the right at velocity Ve, as shown in Fig. below. Find the force required to keep the plate moving at constant velocity if the jet density is 1000 kg/m', the jet area is 3 cm, and V; and V. are 20 and 15 m/s, respectively. Neglect the weight of the jet and plate, and assume steady flow with respect to the moving plate with the jet splitting into an equal upward and downward half-jet. (25 points) p = Pa Cs R, R V, V,-V.
