The basic cooling tower process is outlined in Figure 1. ... The data needed to calculate heat transfer by air cooling and evaporation has been compiled in a graph known as a psychrometric chart.

This month’s B2B focuses on a new cooling tower to serve a pharmaceutical facility’s new process water system. This tower will be a closed-loop, evaporative condenser to operate 24/7/365. The pharma ...

So, with an inlet cooling water flow rate of 150,000 gpm (1,251,000 lb/min), the calculated air flow is 1,248,000 lb/min, which, by chance in this case, is close to the cooling water flow rate.
