Water drives a waterwheel (or turbine) of radius R = 3.0 m as shown in Fig. 8–66. The water enters at a speed vi = 7.0 m/s and exits from the waterwheel at a speed v2 = 3.8 m/s. (a) If 85 kg of water passes through per second, what is the rate at which the water delivers angu- lar momentum to the waterwheel? (b) What is the torque the water applies to the waterwheel? (c) If the water causes the waterwheel to make one revolution every 5.5 s, how much power is delivered to the wheel? FIGURE 8–66 Problem 95.
