Boiler Formulas - Johnston Boil

Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu. What is the factor of evaporation? FE = SH + LH / 970.3 FE = SH + LH / 970.3 FE = ( (338 – 225) + 881) / 970.3 What is the force of 260 lbs of pressure exerted on 8 sq.
