As discussed in class, rotor wheel turbines are commonly used in hydroelectric power plants to generate electric power. In the Pelton wheel design below with radius r = 2 m, a high speed water jet (with Vj = 50 m/s and flow rate 10 m3 /s) impinges on buckets making an angle β=160 degrees, forcing the wheel to rotate at constant angular speed ω = 150 revolutions per minute. Calculate the power delivered to the rotor if there are 10 jets as described above surrounding the Pelon wheel.

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.
