eng.cooling-tower-approach Calculator
Calculates cooling tower approach temperature, range, efficiency, and evaporation rate from wet-bulb temperature and flow data. Cooling tower approach temperature (leaving water − wet-bulb) of 3–5°C is achievable with large fills — it cannot approach zero regardless of tower size.
Inputs
Hot Water Temp C
Reference formula or conversion factor shown for context.
Cold Water Temp C
Reference formula or conversion factor shown for context.
Wet Bulb Temp C
Reference formula or conversion factor shown for context.
Flow Rate L Min
Volume of fluid per unit time. Used to size pipes, pumps, and ducts.
Results
cooling range (°C)
The difference between the maximum and minimum values.
approach temperature (°C)
The value at the specified point or condition.
tower efficiency
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
heat rejected (kW)
The value at the specified point or condition.
