Conversion of air cooler fouling coefficient
Thread Content
Dear experts, I would like to ask whether the unit conversion process for the fouling coefficient of the air coolers below is correct: converting from (h-ft2-°F)/Btu to m2℃/W. 1 Btu/h = 0.293071 W, 1 ft2 = 0.092903 m2, and 1°F = 1.8℃ + 32. Using these values, the calculation gives 0.092903*1.8/0.293071 = 0.570597. However, the value obtained using a professional conversion software is 0.17611. Why is this? ? ?
The temperature conversion part: 1F=1.8C is calculated; it’s actually F=1.8C+32
1 F=1.8℃+32 – this calculation is incorrect. 1F represents a temperature difference of 1.8 degrees
The 1.8°C I wrote here refers to 1.8 multiplied by degrees Celsius; 1.8 is the coefficient.
