Krypton provides high accuracy thermodynamic properties for elemental Krypton using the fundamental equation of state presented in:

R.T. Jacobsen, S.G. Penoncello, and E.W. Lemmon, Thermodynamic Properties of Cryogenic Fluids, Plenum Press, New York ISBN 0-306-45522-6, 1997


The thermodynamic property correlations are valid for temperatures between triple point (115.77 K) and 800 K at pressures up to 300 MPa. 


Range of applicability for transport function correlations:

Gas-phase viscosity:  115.77 K to 800 K 

Liquid-phase viscosity:115.77 to 209.4 K 

Gas-phase thermal conductivity:115.77 K to 800 K

Liquid-phase thermal conductivity: 115.77 to 209.4 K 


The viscosity correlation were fit to data provided from:

E.W. Lemmon, M.O. McLinden and D.G. Friend,
