A jet of steam 40mm in diameter is discharged from a nozzle at a speed of 100m/s. With a specific volume of 3.5 m3/kg. The jet strikes a curved turbine blade, which deflects the steam through an angle of 30°, Ignore frictional loss.

a) the resultant force exerted on the blade by the stream if the blade is stationary

b) the resultant force exerted on the blade if it is moving horizontally at a speed of 50m/s

c) the power developed by the moving blade

A horizontal (x direction +→) water jet from a round nozzle is striking towards right on a curved vane at velocity V = 8 m/s with a flow rate of Q = 160 Liter per minute. The direction of water is turned downwards by 45° from the direction of the striking jet and exiting the vane at the same speed. Calculate the net momentum change (exit - inlet) in the direction of the striking fluid (along x direction towards right→)...
