Problem # 1 The thrust developed to propel the jet ski shown is a result of water pumped through the vehicle and exiting as a high-speed water jet. For the conditions shown in the figure, and 400- lb thrust. Determine (a) inlet velocity [f/s] (b) outlet velocity [ft/s] (c) Volume flow rate [ft'/s] (d) mass flow rate [ lbm /hr ]. Assume the inlet and outlet jets of water are free jet Vin = Vout = 4 in.-diameter outlet jet Q = SEA CHAFT Mass flow rate 30-in. inlet area
