Description

Correlations obtained by linear regression (least squares) are presented for the saturation temperature Ts(P), saturation pressure Ps(T), vaporisation enthalpy Hfg(T), vaporisation specific volume Vfg(T), density of saturated vapour, RHOg(T), saturated liquid dynamic viscosity, MUf(T), saturated vapour dynamic viscosity, MUg(T), and the thermal conductivity of saturated liquid, Kf(T), covering the complete temperature range given in the data source (ASHRAE 1989). The equations produced are compared graphically with the tabulated values and equations given by ASHRAE whenever possible. Figures show the fitted curves, data points, and the resulting errors.
