WebMay 20, 2009 · The heat load is calculated using 969.89 Btu/lb as the latent heat of condensation --- and that is the correct figure to use. Actually, I get 969.74 Btu/lb using the online NIST database - but that nit-picking. You obviously have your enthalpies mixed up. The enthalpy of the saturated condensate at 4.6 in Hg = 181.96 Btu/lb
Get a QuoteWebJun 1, 2008 · The heat load can be conservatively estimated to be equal to the amount of electricity consumed if electricity is the only form of energy entering a system. To determine the heat load more accurately, use the following equation Q = m x Cp x ΔT where Q is the heat load (BTU/hr). m is the mass flow rate (lb/hr). Cpis the specific heat (BTU/lb °F).
