Question

the force exerted by a jet of water on a stationary vertical plate in direction of jet is given by​

Answer 1

Jet strikes the curved plate at the centre. Let a jet of water strike a fixed curved plate at the centre as shown in figure.3. The jet after striking the plate comes out with the same velocity if the plate is smooth and there is no loss of energy due to impact of the jet, in the tangential direction of the curved plate. The velocity at the outlet of the plate can be resolved in to two components, one in the direction of the jet and the other perpendicular to the direction of the jet.
