Question: River water at 700F flowing at 10 mph is diverted into a 30 x 30; channel which is connected to a turbine operated 500 ft below the channel entrance. The water pressure at the channel inlet is 25 psia and the pressure 20 ft below the turbine is atmospheric. An estimate of the lost work in the channel is 90 ft 1bfAbm.
a. Draw a flow diagram showing all control volumes and control surfaces with reference to a zero energy plane.
b. Calculate the horsepower from a 90 percent efficient water turbine.
The cart shown starts from rest and rolls down the slope. For each wheel Ic = 0.8 ft-lb-s^2, weight 30 lb. and diameter 32 in. The body of the cart weighs 60 lb. Assuming no slipping and neglecting friction at the axles, determine the a) accelerat..
