For an ideal gas the internal energy - u - is a function of temperature. A change in internal energy can be expressed as. du = c v dT (1) where. du = change in internal energy (kJ/kg). c v = specific heat for gas in a constant volume process (kJ/kgK). dT = change in temperature (K). Specific heat c v varies with temperature but within …

WebThe isothermal gas compressibility, which is given by the symbol c g, is a useful concept that will be used extensively in determining the compressible properties of the reservoir. The isothermal compressibility is also called the bulk modulus of elasticity. Gas usually is the most compressible medium in the reservoir.
