Data for the viscosity and thermal conductivity of gaseous and liquid propane have been evaluated and represented by empirical functions developed in previous work. Tables of values are presented for the range 140–500 K for pressures to 50 MPa (? 500 atm). The viscosities are estimated to have uncertainties of about ±5%, with corresponding uncertainties of the thermal conductivities of about ±8%. It is stressed that the data base should be improved. As in our work with other fluids, the anomalous contribution to the thermal conductivity in the vicinity of the critical point is included.
