How could we calculate the "X" thermodynamic quality, In order to make a comparison of critical heat flux correlation results with those mentioned in the 2006 CHF look up table .
The thermodynamic quality is defined by the enthalpy from the following expression:
x=(h - h_l,sat)/(h_v,sat - h_l,sat)
where h [J/kg] is the vapor/liquid mixture enthalpy, h_l,sat is the liquid enthalpy at saturation temperature, and h_v,sat is the vapor enthalpy at saturation tempreature. x is the thermodynamic quality, and can in principle be negative and larger than unity. However, for an equilibrion two-phase mixture x will be between zero and unity.
