Figure 16.23 is a sketch of a turbine in which the incom- ing stream of water at 15°C has a diameter of 7.50 mm and is moving with a velocity of 25 m/s. Compute the force on one blade of the turbine if the stream is deflected through the angle shown and the blade is stationary.
Propeller blades in aeroplane are 2 m long. when propeller is rotating at 1800 rev/min, compute the tangential velocity of the tip of the blade.
A jet of water impinges on a single smooth flat vane at its centre. The velocity of the jet is 70 m/s and the diameter 120 mm.Calculate the force on the vane, if it is moving with a velocity of 30 m/s in the direction of jet. Determine the power and efficiency. Also, find the speed of plate at which maximum efficiency may occur.
