Calculating Cooling Tower Efficiency

07/14/2009 7:52 AM

I have all the necessary data with me to find the efficiency of cooling tower. I used the following formula to find out the efficiency of cooling tower but i think it may lead to wrong answer...kindly help me out

Efficiency = (Inlet Temp - Outlet Temp) / (Inlet Temp - Wet bulb temp of air)

Why is the calculation of the efficiency of the cooling tower needed?

The pond temperature will approach, over time, the wet bulb temperature of the air passing though it.

If the wet bulb goes up, the pond temperature will rise, and the return temperature will rise too.

What does efficiency mean in this context, and why is there a need for an equation to express it; of what practical value is it?
