Some common steam and condensate equations can be expressed as
Steam Heating
ms = h / 960 (1)
where
ms = steam mass flow rate (lbs./hr.)
h = heat flow rate (Btu/hr.)
Steam Heating Liquid Flow
ms = ql 500 SGl Cpl dtl / Ls (2)
where
ms = steam mass flow rate (lbs./hr.)
ql = volume flow liquid (gallons per minute, gpm)
SGl = specific heat capacity of the liquid (Btu/lb.oF)
Cpl = specific gravity of the fluid
dtl = temperature difference liquid (oF)
Ls = latent heat steam (Btu/lb)
Steam Heating Air or Gas Flow
ms = qg 60 ρg Cpg dtg / Ls (3)
where
ms = steam mass flow rate (lbs./hr.)
qg = volume flow gas (cubic feet per minute, cfm)
ρg = density of the gas (lb/ft3)
Cpg = specific gravity of the gas
dtg = temperature difference gas (oF)
Ls = latent heat steam (Btu/lb)
