s_LiBrH2O
Function s_LiBrH2O(T, x) returns the specific entropy for a liquid solution of lithium bromide and water as a function of the mixture temperature, T and composition, x.
The temperature, T, is assumed to be in the temperature units specified in the EES Unit System dialog, which can be C, K, F, or K.
The composition, x is assumed to be the lithium bromide mass fraction if EES is configured to operate with specific properties on a mass basis. If EES is configured to operate on a molar basis, x is assumed to be the lithium bromide mole fraction.
s_LiBrH2O is returned in the unit system EES has been configured to operate in, which can be J/kmol-K, kJ/kmol-K, J/kg-K, kJ/kmol-K, Btu/lbmol-R or Btu/lbm-R.
The function is based on the correlation provided by:
