Consider a water sprinkler as in Figure Q2(b). The mass flow
rate going into the
sprinkler from the base is 4.5 kg/s. The radius at the Outlet 1 and
Outlet 2 is 4 cm and
7 cm respectively, with the water discharges to the atmosphere at
the velocity of 0.75
m/s at Outlet 1. If the sprinkler is rotated at a speed of 150 rpm
at clockwise direction,
determine the power produced by the sprinkler.
