Download Solution PDFExplanation:
Equivalent evaporation is the amount of water evaporated "from and at 100°C" into dry and saturated steam at 100°C at a standard pressure of 1.01325 bar.
The equivalent evaporation from and at 100°C is given by:
The equivalent evaporation = \(\frac{{Total\;heat\;required\;to\;evaporate\;feed\;water}}{{2257}}\)
Total heat required to evaporate 'm' kg of water:
\(E = m\left( {h - {h_f}} \right)\)
Where hf = sensible heat of feed water or fluid enthalpy
h = total heat of steam in kJ/kg at given working pressure.Last updated on Jul 1, 2025
