Experimental data of the thermophysical properties of 3He were mined into a searchable database. Equilibrium equations along the vapor-liquid and liquid-solid lines were proposed. A general equation of state for normal fluid 3He based on the Debye specific heat model was developed. Calculations by the Debye fluid 3He state equation differ from the reference experimental data generally within +/-1% for the p-v-T, +/-0.9% for the specific heat and +/-1% for the velocity of sound. A graphical computer program was developed to simplify the calculation of 3He properties in a wide range for temperature from 0.01 K to 300 K and pressures up to 15 MPa. 3He T-s and p-h diagrams were plotted.
