The waterwheel in Fig. P3.162 is being driven at 200 r/min by a 150-ft/s jet of water at 20 8 C. The jet diameter is 2.5 in. Assuming no losses, what is the horsepower developed by the wheel? For what speed V r/min will the horsepower developed be a maximum? Assume that there are many buckets on the waterwheel. 75 4
