Description
The method for calculation of integral thermodynamic characteristics of the liquid solutions of 3He-4He basing on common equation of state built on basis of obtained at NSC KIPT experimental data is described. Entropy (S), free energy (F), enthalpy (H), Gibbs thermodynamic potential (G) and total energy (E) for solution with concentration 40% 3He for the temperatures 2,25...4,2 K and pressures 0...10 MPa are calculated with temperature and pressure increment sufficient for linear interpolation of the data. This calculation is the stage of the complication of engineering tables of thermodynamic characteristics of liquid 3He-4He solutions that have a great value for thermal calculations of the low-temperature cryostats, basing on the method of 3He dissolving in 4He.
