The water in a large lake is to be used to generate electricity by the installation of a hydraulic turbine generator at a location where the depth of the water is 50 m. Water is to be supplied at a rate of 5000 kg/s. If the electric power generated is measured to be 1862 kW and the generator efficiency is 95 percent, determine (a) the overall efficiency of the turbine-generator, (b) the mechanical efficiency of the turbine, and (c) the...

9) Electrical power is to be generated by installing a hydraulic turbine-generator at a site 70 m below the free surface of a large water reservoir that can supply water at a rate of 1500 kg/s steadily. If the mechanical power output of the turbine is 800 kW and the electric power generation is 350 kW, determine the turbine efficiency and the combined turbine-generator efficiency of this plant. Neglect losses in the pipes. (10pts).

6. Determine the power required for a 5000-kg car to accelerate from 5m/s to 20m/s in 10 seconds. (Show the formula and procedures.) 7. For a hydroelectric plant, a hydraulic turbine-generator is installed at the site below the free surface. The turbine drives a generator for electricity. The elevation difference between the two free surfaces is h = 60m. The mass flow rate of water is th = 300kg/s. The shaft power output from the turbine is W. = 87kW....

Water flows with a volumetric flow rate of 65 m'ls to a turbine, where electric power is generated. The total irreversible head los in the piping system from point 1 to point 2 (excluding the turbine unit) is determined to be 95 m. The pressure difference due to elevation cannot...

In an impulse turbine of the Pelton type, the jet is turned by the bucket by 165°. The head available at the nozzle is 750 m and blade speed ratio is 0.46. Cv = 0.98. Relative velocity is reduced by 12% due to friction. Determine the hydraulic efficiency. If the flow available is 20 m3/s. What is the power potential. Assuming 5 units of equal power, determine the jet diameter and wheel diameter if d/D = 12.

A coal-fired steam power plant produces 175 MW of electric power. The power plant operates on a Rankine cycle with turbine inlet conditions of 7 MPa and 550oC and a condenser pressure of 15 kPa. The turbine efficiency and pump efficiency are both 0.8. The coal has a heating value (energy released when the fuel is burned) of 29,300 kJ/kg. Assuming that 85 percent of this energy is transferred to the steam in the boiler and that the electric generator...

Problem 2 (Marks 3) AGL Energy is expanding the capacity of the Liddell Power Station. The plan is to commission a steam turbine power plant that operates on a regenerative Rankine cycle and has a net power output of 150 MW where steam enters the turbine at 10 MPa and 500°C, and the condenser at 10 kPa. The isentropic efficiency of the turbine is 80 percent, and that of the both pump is 95 percent. Steam is extracted from the...
