Two functions have been implemented for Calculation of Enthalpy and LiBrH2O Concentration from Curve-Fitting Equations under the specified range as specified on F30. Thermo-physical Properties of Refrigerants from ASHRAE.

Please read the paper for executing this functions

Function details:
1. x = LiBrH2O(t,p);
Function LiBrH2O calculates the concentration for the corresponding Lithium Bromide - Water solution temperature and Saturation Pressure, within the range as per as curve-fitting equation.

INPUTS:
p = Saturation Pressure in kPa
t = Lithium Bromide - Water solution temperature in degree-Celsius
OUTPUT:
x = concentration of Lithium Bromide - Water solution in kJ/kg

2. h = EqLiBrH2O(x,t);
Function EqLiBrH2O calculates the Enthalpy for the corresponding concentration and temperature of Lithium Bromide - Water solution, within the range as per as curve-fitting equation.

INPUTS:
x = Lithium Bromide - Water solution concentration in percent
t = Lithium Bromide - Water solution temperature in degree-Celsius
OUTPUT:
h = Enthalpy of Lithium Bromide - Water solution in kJ/kg
