Heat of vaporization: 1336.97 kJ/kg at the boiling point. The specific heat capacity at constant volume of the gas is 1.624 kj/(kg•K) at 25°C. 1.624*48=78; 1.700/(1337+78)=1.2 kg/s, which equals 4.3 tons/h
Could you explain the meaning of each term in the formula?
“1.624*48=78” This is the calculation for sensible heat; specific heat * weight * temperature difference. 1336.97 kj/kg is the latent heat
