Popis:	Analytical forms of the empirical equations of state of the system are obtained for an equimolar 3He–4He mixture in the homogeneous liquid and dense fluid phases at temperatures 1.5–14 K and pressures 0–10 MPa on the basis of the existing experimental P–V–T data. This is done by choosing approximating expressions, setting up a computer program, and calculating the fitting coefficients of the expressions. The quality of the approximation corresponds to the accuracy of the experimental determinations and is on average 0.5%.
