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.
A motor-pump system with 90% efficiency is designed to increase the pressure of was from 101kPa to 250 kPa while water is flowing at a rate of 2 m^3/s. Assuming no change in the kinetic and potential energy of water, what is the expected electric power usage of the system?
An air compressor draws air from the atmosphere and discharges it at 500 kPa through a 100 mm-diameter outlet at 100 m/s. Determine the minimum power required to drive the insulated compressor. Assume atmospheric conditions of 25 C and 80 kPa.
Water with a specific volume of 0.001 m3×kg-1 flows through a centrifugal pump that operates under steady flow conditions at a volumetric flow rate of 3.0 m3×min-1 from an initial pressure of 75 kPa to a final pressure of 220 kPa. The diameter of the suction inlet to the pump is 12 cm and the diameter of the discharge outlet is 8 cm. If the suction and discharge outlets are at the same level and no change in internal energy, determine the work (HP) done on the water by the pump.
Why does a pressure change in a turbine that is not reversible calculated this way?. why we can just put T4s as an input? thank you very much
An inventor claims to have designed a 4 m diameter horizontal-axis hydrokinetic turbine that can produce 3.8 kW from a current flow of 3 m/s. Do you believe the claim?
Give examples of pump efficiency and turbine efficiency?
Solve the problem. A reciprocating compressor draws in 500 cubic feet per minute of air whose density is 0.079 lb/cu ft and discharges it with a density of 0.304 lb/cu ft. At the suction, pressure is 15 psia, at discharge pressure is 80 psia. The increase in the specific internal energy is 33.8 Btu/lb and the heat transferred from the air by cooling is 13 Btu/lb. Determine the work on the air in Btu/min and in hp. Neglect change in kinetic energy.
