# Specific Enthalpy

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Specific enthalpy, abbreviated as h, is the enthalpy per unit mass.  It is also the total specific internal energy in a system and the product of pressure and specific volume.

### Specific Enthalpy formula

$$\large{ h = \frac{H}{m} = u + p \; v }$$

Where:

$$\large{ h }$$ = specific enthalpy

$$\large{ H }$$ = enthalpy

$$\large{ m }$$ = mass

$$\large{ p }$$ = pressure

$$\large{ u }$$ = specific internal energy

$$\large{ \upsilon }$$   (Greek symbol upsilon) = specific volume
