The thrust developed to propel the jet ski shown in Video V9.18 and Fig. P5.71 is a result of water pumped through the vehicle and exiting as a high-speed water jet. For the conditions shown in the figure, what flowrate is needed to produce a 300-1b thrust? Assume the inlet and outlet jets of water are free jets.
