Incomplete Question :-
A water jet of 0.002 m² in area issues from a nozzle with 20 m/s velocity. It impinges perpendicularly on a plate that is moving with a velocity of 5 m/s. The force on the plate due to impact of jet is:
Answer :-
Force = p A (V - u)²
Force = 1000 x 0.002 x (20 -5)²
Force = 1000 x 0.002 x 15²
Force = 2 x 225
Force = 450 N
