YEAR / SEMESTER - II / IV Max 20 marks Date: 10-01-2014

1. A jet of water of 5 cm diameter with a velocity of 12 m/s strikes a fixed curved vane at an angle of 35° and the jet leaves the vane at an angle of 20°. If there no frictional losses, find the normal and tangential forces of the jet on the vane. (5)

2. Derive an expression for the force exerted by a jet of water on hinged plate (5)

3. A jet of water of diameter 50 mm strikes a stationary, symmetrical curved plate with a velocity of 40 m/s. Find the force extended by the jet at the centre of plate along its axis if the jet is deflected through 120o at the outlet of the curved plate. (5)

4. A plate is acted at its centre by a jet of water of diameter 20 mm with a velocity of 20 m/s. The plate is hinged and is deflected through an angle of 15°. Find the weight of the plate. If the plate is not allowed to swing, what will be the force required at the lower edge of the plate to keep the plate in vertical position (5)
