Specific Enthalpy

  1. Feb 4, 2009 #1
    I read that for an ideal gas, the specific enthalpy (h) at constant pressure is equal to the specific internal energy of the gas. How do I proof that?

    I know that:

    1.) specific enthalpy = specific internal energy + pressure x specific volume

    2.) Internal energy at constant pressure = mass of gas x capacity x change in tempt. + (pressure x volume of gas)

    3.) pressure x specific volume = gas constant x temperature

    How do I obtain specific internal energy? Do I simply divide both sides by (m)?

    How do I proceed on after I've obtained specific internal energy?

    Where did you read this? It doesn't sound right, as written.
