Answer to Question #52598 in Molecular Physics | Thermodynamics for ando
A hydroelectric power station requires water to be pumped from dam A to dam B, using two pumps (each consuming 250MW of power at 98% efficiency) to elevate the water approximately 70m. At full power, dam B can be filled from empty to its capacity of 28700 ML in 14 hours. The water being supplied us stationary at 4 atm and 10 deg C; it is released at 1atm through a pipe of 20m in diameter. Assuming there will be no heat transfer to the water. What is the maximum temperature at which the water will exit?
