Show that force exerted by jet of water on inclined fixed flat in direction of jet is given by FX =Rohav^2sin^2

Show that force exerted by jet of water on moving inclined plate in direction of plate is given by.

A jet of water of diameter 50 mm having velocity of 30 MPs strikes acre wave which is moving with a velocity of 15 MPs in the angle direction of state the jet lose the When at angle of 60 degree to the direction of motion of vanes at outlet. Determine- 1. Force exerted by jet on vane in direction of motion. 2. Workdone per sec by jet.

A jet of water having velocity of 30 m/s strikes a series of radial curve vane mounted on wheel which is rotating at 500 rpm the jet mix angle of 30 degree with tangent to wheel Intel and leaves the wheel with velocity show 4 m/s data on angle of 120 degree toward tangent to the wheel at outlet water is flowing from outwards in radial direction the outer and inner radius of wheel are 0.6 m & 0.3m & inner of wheel are 0.6m & 0.3 m respectively. Determine- 1.vane angle at inlet & outlet. 2.W D per sec kg of water. 3. Efficiency of wheel.

A jet of water of 30 mm diameter of moving with velocity of 15 m/s strikes a hinge square plate of win 245.23 N at the centre of the plot the plate of uniform thickness. Find the angle through which the plate will swing.

Prove that the work done per second on series of moving car wins by jet of water striking one of the tip of when is given by WD/sec= rhow av1(vw1 + vw2)X u.
