【Abstract】 Overcoming the difficulty of calculations of known equation of saturated liquid density of fluids in the critical and enlarged critical region, a new generalized equation of saturated liquid density is developed. The equation presented here can valid over the entire range from the triple point to the critical temperature for nonpolar and polar fluids, refrigerants, associating compounds. Only the critical parameters To, ρc, Zc are needed in the prediction of saturated liquid density. Compared with experimental values for 644 data, an average overall root mean squares and maximum deviation are 0.327%, 0.662%, respectively.更多还原
