The recent PVT measurements of p‐hydrogen reported by the National Bureau of Standards (1,2,3) have been utilized to establish the Enskog modulus, bpx , for pressures up to 350 atm and temperatures up to 100°K. These conditions define both the gaseous and liquid regions and also include the saturation envelope from the triple point to the critical point of this substance. This modulus is expressed graphically as a function of reduced pressure and reduced temperature. The best available PVT measurements coupled with a precise calculational procedure conducted on an IBM 709 computer have produced a bpx correlation which readily permits the calculation of the pressure dependence of the transport properties of p‐hydrogen according to the Enskog theory for the dense gaseous and liquid regions.
