Wаter flоws thrоugh а turbine аt a rate оf 20 m3/s to produce electric power. The turbine has a mechanical efficiency of 0.95 and delivers 9 MW of shaft power to the generator, which has an efficiency of 0.96. The water pressure at the inlet of the turbine is measured to be 600 kPa. Assume the density of water to be constant at 998 kg/m3. (a) The water pressure at the exit of the turbine is [P2] kPa. (round to one decimal place) (b) The generator produces [We] MW of electric power. (round to two decimal places) (c) The overall efficiency of the turbine-generator assembly is [eo]. (round to three decimal places) (d) The total amount of power lost as heat dissipation from the turbine-generator assembly is [Q] MW (round to three decimal places) (e) If instead of taking the high-pressure water thru a turbine to produce power, we use the high pressure to raise the water to a water tower where it will discharge at a pressure of 100 kPa, what is the height of the tower assuming no energy is lost? The height of the tower is [h] m (round to the nearest integer)
