# Isobaric Process - Enthalpy

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Isobaric process is a thermodynamic process where the pressure is kept constant, $$\Delta p = 0$$.

## Isobaric process - enthalpy Formula

 $$\large{ H = C_p \; \left( T_2 - T_1 \right) }$$

### Where:

 Units English Metric $$\large{ H }$$ = enthalpy $$\large{\frac{Btu}{lbm}}$$ $$\large{\frac{kJ}{kg}}$$ $$\large{ C_p }$$ = heat capacity at constant pressure $$\large{\frac{Btu}{F}}$$ $$\large{\frac{kJ}{K}}$$ $$\large{ T_1 }$$ = temperature at state $$\large{F}$$ $$\large{K}$$ $$\large{ T_2 }$$ = temperature at state $$\large{F}$$ $$\large{K}$$
