The efficiency of a thermal power plant improves with.

a. increased quantity of coal burnt

b. Use of high steam pressure

c. Lower load on the plant

d. Larger quantity of water used

If we assume the efficiency as 70 % then what would be the kinetic energy resulted from the 180 kcal of chemical energy?

During a flow of 500 liters, the gage pressure is 68 kPa in the horizontal 300 mm supply line of a water turbine. A 41 kPa vacuum is measured at a 450 mm section of draft tube 2 m below the turbine. Assuming an efficiency of 85%,

a. Compute the total head extracted by the turbine.

b. Compute the output horsepower of the turbine.

c. Compute the input horsepower of the turbine.
