A speedboat is powered by the jet drive shown. Seawater is drawn into the pump housing at the rate of 20 ft3 /s through a 6-in.-diameter intake A. An impeller accelerates the water flow and forces it out horizontally through a 4-in.- diameter nozzle B. Determine the horizontal and vertical components of thrust exerted on the speedboat. The specific weight of seawater is . y sw = 64.3 lb/ft3
