In a pelton-wheel turbine, a stream of water isdeflected by a
series of blades so that the rate at which water isdeflected by the
bldes is equal to the rate at which water issuesfrom the nozzle
a using the same nottation as insample prob. 14.7 (a)
determine the velocity v of the blades forwhich maximum power is
developed, b) derive an expression for themaximum power, c) derive
an expression for the mechanicalefficiency.
