(Moment-of-momentum) A small water turbine is designed as shown in the figure below. If the flowrate through the turbine is 0.00331 slugs/s, and the rotor speed is 293 rpm, estimate the (a) shaft torque and (b) shaft power involved. Each nozzle exit cross- sectional area is 3.5x10-5 ft. (a) i ftlb (b) i ftlb + 3 in.. O Nozzle exit area = 3.5 x 10-5 ft
