(a) For a Pelton wheel, a jet of cross section area $0.15 \mathrm{~m}^{2}$ is discharging through the nozzle at the rate of $0.18 \mathrm{~m}^{3} / \mathrm{s}$ under a head of 32 m . The shaft power is 44 kW and mechanical efficiency is $94 \%$. Calculate the power lost (i) in the nozzle and (ii) in the runner.
Explanation
The power lost in the nozzle and the runner can be calculated using the equations for power loss in the nozzle and the runner. The power lost in the nozzle and the runner is given as 2.68 kW.
