Enthalpy - thermodynamics, Mechanical Engineering

Assignment Help:

Enthalpy:

Sol: The enthalpy is total energy of gaseous system. It takes into consideration, internal energy and pressure, volume effect. Thus, it can be defined as follows:

h = u + Pv

H = U + PV

Where v is specific volume and V is the whole volume of m Kg gas. h is specific enthalpy where as H is total enthalpy of m kg gas u is specific internal energy while U is total internal energy of m kg gas. From ideal gas equation,

Pv = RT

h = u + RT

h = f (T) + RT
Thus, h is also function of temperature for perfect gas.

Therefore, h is also function of temperature for the perfect gas.
