Question: A power plant having a Carnot efficiency produces
A power plant, having a Carnot efficiency, produces electric power from turbines that take in energy from steam at temperature Th and discharge energy at temperature Tc through a heat exchanger into a flowing river. The water downstream is warmer by ΔT due to the output of the power plant. Determine the flow rate of the river.
