For the steam and condensate at 300 kPa, hs = 2,725 kJ kg-1, hc = 561 kJ kg-1 and the steam temperature is 133.5°e. The enthalpy of feed at a temperature of 18 °C is hF = 75.5 kJ kg-1. Taking atmospheric pressure to be 101.3 kPa, the pressure within the evaporator is 22.0 kPa and therefore the evaporator temperature (assuming no boiling point elevation) is 62.2 °C. Consequently hv = 2,613 kJ kg-1 (hg at 0.22 bar) and hL = 260 kJ kg-1(hf at 0.22 bar).
