Question:
An electric power plant generates \(500 \mathrm{MW}\) of electric power and operates at a thermal efficiency of 38 percent. The waste heat from the power plant is transferred to the environment from a cooling pond that is \(2000 \mathrm{~m}\) wide and \(2000 \mathrm{~m}\) long. Assuming conditions are steady, an ambient temperature of \(T_{\infty}=20^{\circ} \mathrm{C}\), and a relative humidity of 50 percent, determine the pond water temperature if a breeze of \(3 \mathrm{~m} / \mathrm{s}\) flows parallel to a side of the pond. What is the heat loss rate from the pond by convection? What is the heat loss rate due to evaporation? Conditions are turbulent everywhere. Assume radiation heat transfer is negligible.
