Q6 a) b) Q7 a) b) Q8 a) b) c) d) A pelton wheel has a mean bucket speed of 12 m/s and is supplied with water at the rate of 750 lits/sec under a head of 35 m. If the bucket deflects the jet through an angle of 1600, find the power and efficiency of the turbine. Take the coefficient of velocity as 0.98. Explain with the help of a sketch the working of a reciprocating pump. (6) With a sketch, explain the constructional features of a modern Francis turbine. A centrifugal pump impeller is 40 cm in outer diameter and 2.5 cm wide at exit and its blade angle is 1500. When run at a speed of 2100 r.p.m, the flow rate through the pump is 80 lit/sec. Calculate the radial, relative and absolute fluid velocities at the impeller exit. (4) (6) Write short notes on any two of the following. Fluid classification Pitot tube Multistage centrifugal pumps Indicator diagram (4) (5 x 2)
