A nozzle of 50 mm. dia. delivers a stream of water that strikes a flat plate which is held normal to the axis of stream. If the issuing jet has a velocity of 15 m/sec.,
Determine:
(i) Force exerted on the plate, if plate held stationary.
(ii) Work done per second, if plate held stationary.
(iii) Jet efficiency, if plate if plate moves in the direction of jet at 5m/sec.
(iv) Work done if plate is replaced by a series of plate moving with a velocity 5m/sec.
