Water drives a waterwheel (or turbine) of radius R = 3.0 m as shown in the figure. The water enters at a speed v1 = 6.5m/s and exits from the waterwheel at a speed v2 = 3.0 m/s.
(a) If 165 kg of water passes through per second, what is the rate at which the water delivers angular momentum to the waterwheel?
kg·m2/s2
(b) What is the torque the water applies to the waterwheel?
m·N
(c) If the water causes the waterwheel to make one revolution every 5.5 s, how much power is delivered to the wheel?
W
