1. How to Compile
-------------------------------------------------------------------------
Make sure you have a Fortran compiler installed (like gfortran).
Run the following compilation command in your terminal:

  gfortran -ffree-line-length-none steam.f90 steam_calc.f90 -o steam_calc

-------------------------------------------------------------------------
2. How to Execute
-------------------------------------------------------------------------
Run the compiled binary and redirect the input.txt file into stdin:

  steam_calc < input.txt

3. Input File Details
-------------------------------------------------------------------------
The input file 'input.txt' contains sequential parameters separated by
newlines. Here is the structure of the included 'input.txt':

  Line 1 (Input combination mode (1=T/P, 2=T/x, 3=P/x, 4=P/h, 5=P/s)): 1
  Line 2 (Parameter 1 (Temperature [°C] or Pressure [kPa])): 150.0
  Line 3 (Parameter 2 (Pressure [kPa] or Quality [0-1] or Enthalpy [kJ/kg] or Entropy [kJ/kg-K])): 101.325
