(10%) Problem 4: A water wheel with radius Rw = 13 m and mass MW = 1.05 x 103 kg is used to power a grain mill next to a river. Treat the water wheel as a hollow cylinder. The rushing water of the river rotates the wheel with a constant frequency f, = 1.5 Hz. Randomized Variables Rw=13m Mw=1.05x103 kg fr=1.5Hz & 33% Part (3) Calculate the angular velocity ww of the water wheel in radians/sec. a 33% Part (b) Calculate the kinetic energy Kw, in J, of the water Wheel as it rotates. D 5 33% Part (c) Assume that every second, 20% of the kinetic energy of the water wheel is transmitted to the grain mill. Calculate the power PW in W of the grain mill based on the energy it receives from the water wheel. Grade Summary Pw = | Deductions 0% 100% Potential
