A mini hydro power station takes in 3 cubic meters per second of water from a wide open reservoir through its turbine from an elevation of 15 meters and discharges to its surroundings at 0.50 m/s. During data gathering, the rotational force of the turbine shaft is measured 250 N for a distance of 2 m from its center axis at 2,850 rpm. If the electrical generator is 88% efficient, determine the turbine efficiency and the electrieity output of this station. Show the energy or schematie diagram and label it accordingly.

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.
