During the test of a Pelton wheel, the pressure at the end of the 6.10" diameter nozzle was 515 psig when the flow is 2,615 ft/min. The peripheral coefficient is 0.46, the turbine specific speed is 6.20 rpm, and the penstock diameter is 1.5 feet. If the mechanical efficiency is 86% and electrical efficiency is 85%, determine the diameter of wheel in feet.

The pump draws oil with specific gravity of 0.90 from a reservoir and delivers it to the hydraulic cylinder. The cylinder has an inside diameter of 5.0 inch and in 15 seconds the piston must travel 20 inches while exerting a force of 11,000 lb. It is estimated that there are energy losses of 11.5 lb-ft/lb in the suction pipe and 35.0 lb-ft/lb in the discharge pipe. Both pipes are 3/8-in Scheulde 80 steel pipe with inside diameter of 0.423 inch. Calculate the pressure at the cylinder.
