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

  gfortran -O3 nozzle_flow.f90 -o nozzle_flow_calc

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

  nozzle_flow_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':
