(a) Describe the terms "Fluid jet" & "Vane" in Fluid Machine.
(b) What is impulse - momentum principal in analysis and design of turbo machines.
What are the assumptions made during calculation of force exerted by jet on the plate ?
(b) A jet of water which has diameter of 8 cm. issues with a velocity of 40 m/sec. and impinges on a stationary flat plate which destroys its forward motion completely. Determine force exerted by the jet on the plate and work done ? (take density f water 1000 Kg/m^{3}).
