Units and Factors
t = temperature in °F
P = pressure in lb/in2 absolute (psia)
Cp = Heat capacity at constant pressure in Btu/(lbm-°R)
Cv = Heat capacity at constant volume in Btu/(lbm -°R)
Cp/Cv = Heat capacity ratio (dimensionless)
μ = Viscosity in centipoise
ν = Kinematic viscosity in centistokes
k = Thermal conductivity in Btu/(hr-ft-Btu/(lbm -°F)c = Velocity of sound in ft/sec
γ = Surface Tension in lbf/ft
hf = enthalpy of saturated liquid in Btu/lb
sf = entropy of saturated liquid in Btu/(lb) (°R)
One atmosphere = 14.696 psia
Reference point for enthalpy and entropy:
hf = 0.0 Btu/lb at -40°F
sf = 0.0 Btu/lb-°R at -40°F
This information is based on NIST Standard Database 23, Version 9.1 (Lemmon, E.W.; Huber, M.L.;
McLinden, M.O.; REFPROP Reference Fluid Thermodynamic and Transport Properties - National
Institute of Standards and Technology, 2013) using Chemours interaction parameters with R-1234yf.
