Heat Capacity at Constant Pressure
At constant pressure, abbreviated as Cp, some of the heat goes to doing work. The value of heat capacity depends on whether the heat is added at constant volume, constant pressure, etc.
Some Cp values for gasses can be found here (SI Units) or here (US Units).
Heat Capacity at Constant Pressure Formula
| \(\large{ Q = n \; C_p \; \Delta T }\) |
Where:
\(\large{ Q }\) = heat transfer, [kJ or BTU]
\(\large{ n }\) = amount of substance [kg or lbm]
\(\large{ C_p }\) = heat capacity at constant pressure [kJ/(kg K) or BTU/(lbm F)]
\(\large{ \Delta T }\) = temperature differential
