Q7 (a) With neat sketch, derive an expression for minor loss due to sudden enlargement. Also comment on the value of loss coefficient in case of no area change and discharge into reservoir from the expression. (b) A fluid jet strikes at the center of a symmetrical moving smooth curved vane. Find an expression for the efficiency of the vane. What will be the efficiency if the vane is a semicircle and the velocity of the jet is three times the velocity of the vane? I need the proofs in detail,so i kindly request you to write all the steps and calculations and to draw all the necessary figures. I request you again not to skip any step.
