Energy Transfer Equation

Sponsored Links

The energy transfer of a substance can be expressed as

Q = m c_p dt             (1)

where

Q = quantity of energy transferred (kJ, Btu)

m = mass of substance (kg, lb)

c_p = specific heat of the substance (kJ/kg^oC, kJ/kg^oK, Btu/lb ^oF)

dt = temperature difference (rise or fall) in the substance (^oC, K, ^oF)
