Program Supplies Properties Of Parahydrogen

National Bureau of Standards Parahydrogen Properties Database (NBS+_PH2) computer program developed to provide selected thermal and transport properties of parahydrogen matching 1981 parahydrogen data of National Bureau of Standards (now called National Institute of Standards and Technology). Created to be linked with propulsion-simulation programs, which require mathematical model of parahydrogen covering wide range of pressures and temperatures. Provides data on parahydrogen for pressures from 10 kPa to 16 MPa and temperatures from 20 to 104 K. Provides following properties: density, thermal conductivity, viscosity, Prandtl number, enthalpy, specific heat, and speed of sound. Written in FORTRAN 77.
