How does the Cooling Tower Calculator work?

Calculate: Q = m×cp×ΔT where ΔT is cooling temperature drop Then: Approach = outlet temp - wet-bulb temp (typically 2-4°C) Then: Size tower for required cooling capacity.

Can you give an example of how to use the Cooling Tower Calculator?

Example: Input Q = 500 kW, water flow 60 kg/s, approach 3°C, wet-bulb 25°C gives a result of Tower outlet ≈ 28°C, inlet 36°C (6°C drop required).
