Heat transfer rate for steam condensation at atmospheric pressure
Thread Content
At atmospheric pressure, there is 120,000 m3 of saturated steam at 100°C entering, and it is intended to be cooled from 30°C to 50°C by water. How should the heat transfer amount be calculated? Use the enthalpy difference directly? It’s not possible to find out what the steam enthalpy value is. Can water still be condensed from the gas after it has been cooled to 50°C?
Steam at 100 degrees turning into water at 100 degrees (latent heat) + water at 100 degrees turning into water at 50 degrees (sensible heat) = heat transfer amount, which can be expressed using the enthalpy difference.
