A water jet with velocity Vjet impinges normal to a moving flat plate with velocity Vplate such that the jet splits equally into two halves as shown in Figure. The jet cross-sectional area is 2 cm², Vjet is 20 m/s and V plate is 10 m/s and density of water is 1000 kg/m³. Consider steady flow and neglect weight of the jet, weight of the plate and frictional losses. The absolute value of the force required to keep the plate moving at constant velocity V plate is N.
