Question

When the total heat of steam is hkJ/kg and the sensibe heat
of feed water is hf. kJ/kg, then the factor of evaporation is

​

Answer 1

If heat is further added to water, its temperature starts rising again and .... Cp = Specific heat at constant pressure = 0.4 to 0.5 kJ/kg-K ... Dry Steam: Work of evaporation = p (vg – vf).
