Jet strikes on inclined flat moving plate

Let us consider an plate which is free to move linearly and inclind at at an angle θ. The jet of water is striking at the centre of the plate horizontally. Mass flow rate of water Jet is denoted by 'm' in Kilogram per second. As we know the plate is moving with velocity U with respect to ground and velocity of water Jet at entry of plate is V1 with respect to ground. m1 is the mass flow rate exiting from the above end of the plate and m2 is the mass flow rate exiting from the below end of the plate. Point2 denote both the the above and below exit point of jet on the plate. Point1 is the entry point of jet on the centre of plate. U1' represent velocity of entry point of plate and 'U2' represent velocity of exit point of plate. When Jet strikes the plate, it will move in linear direction so here U = U1 = U2. Now in this case also concepts of relative velocity will be used.

V1 represents velocity of jet at entry with respect t…
