1. A Pelton wheel of 4 m diameter operates with a head of 1000 m. Estimate the flow rate and power output of the machine, assuming that it operates at peak efficiency and there are no losses in the flow upstream of the turbine. 2. A Pelton wheel operates with a head of 400 m at 350 rpm, and it is powered by a jet 12 cm in diameter. Find the specific speed (U.S. customary units), and the wheel diameter, if there are no losses in the flow upstream of the turbine and it operates at peak efficiency.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
