Question
1. A large electrical power facility produces 1600 MW of “waste heat,” which is dissipated to the environment in cooling towers by warming air flowing through the towers by $5.00 ^\circ\textrm{C}$. What is the necessary flow rate of air in $\textrm{m}^3\textrm{/s}$?
2. Is your result consistent with the large cooling towers used by many large electrical power plants?
1. $3.4 \times 10^5 \textrm{m}^3\textrm{/s}$
2. This volume flow rate is unrealistically large. The tower diameter would be 177 m, with fans blowing 50 km/h.
