i think i can do something like this , but instead of the equations i've created arrays with the thermodynamic properties ( for saturated r134a ) it takes temperature , and output all the values for this temperature and added a function for interpolation if the needed temperature is not listed with a range of ( -40 to 100 C ) , i can make one from the pressure table .
