We covered Cooling Tower Calculations in our previous post, and to make the process easier for students and working professionals, we’ve created an Online Cooling Tower Calculator.
This tool helps you quickly calculate cooling tower approach, efficiency, and evaporation loss, and is now part of our growing list of chemical engineering calculators on ChemicalTweak.
Range and Approach Calculator
Cooling Tower Calculator
Calculate range and approach for your cooling tower system
Example
Water enters a cooling tower at 40°C and leaves at 32°C. The ambient wet-bulb temperature at the site is 28°C. Calculate the cooling range, the approach and the cooling tower efficiency.
Step 1: Calculate Range
Range = Hot water temperature − Cold water temperature
Range = 40 − 32 = 8°C
Step 2: Calculate Approach
Approach = Cold water temperature − Wet bulb temperature
Approach = 32 − 28 = 4°C
Step 3: Cooling Tower Efficiency
![\[\text{Cooling Tower Efficiency} =\left( \frac{\text{Range}}{\text{Range} + \text{Approach}} \right) \times 100\]](http://chemicaltweak.b-cdn.net/wp-content/ql-cache/quicklatex.com-382e2a692eb3da9f6ede5b40bf1d6488_l3.png "Rendered by QuickLaTeX.com")
![\[= \left( \frac{8}{8 + 4} \right) \times 100\]](http://chemicaltweak.b-cdn.net/wp-content/ql-cache/quicklatex.com-20e248961e0dc8df933dc938444209c8_l3.png "Rendered by QuickLaTeX.com")
![\[= \left( \frac{8}{12} \right) \times 100\]](http://chemicaltweak.b-cdn.net/wp-content/ql-cache/quicklatex.com-33421730361aa7ee7113a8975821c188_l3.png "Rendered by QuickLaTeX.com")
