Request the calculation formula for the evaporation rate of circulating cooling water
A very simple calculation formula: E = W × (ΔT/560), where E is the evaporation rate in t/h, W is the water circulation rate in t/h, and ΔT is the temperature difference between the inlet and outlet water℃； Compared with the results obtained using the strict enthalpy difference method, the errors produced by this formula are completely acceptable; it is also very simple. A temperature difference of 5.6°C corresponds to approximately 1% of the amount of circulating water that needs to evaporate. In fact, this value of 560 represents the latent heat of vaporization of water, and an average value can be taken for temperatures between 30–40°C, with the unit being kcal/kg.
