Question
A jet of water from a fixed nozzle has a diameter of 25 mm
and strikes a flat plate at an angle of 30° to the normal to the
plate. The velocity of jet is 5 m/s and surface of plate in
frictionless. Calculate the force exerted normal to the plate :
(i) If the plate is stationary and
(ii) If the plate is moving with a velocity u of 2 m/s in the
same direction as the jet.
