Calculator : Boundary Layer Thickness & Friction
Category   : Fluid

Files Included:
  - boundary_layer.f90 (Fortran Source Code)
  - input.txt (Pre-configured Sample Input)

-------------------------------------------------------------------------
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 boundary_layer.f90 -o boundary_layer_calc

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

  boundary_layer_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 (Velocity ($U_\infty$) [m/s]): 5.0
  Line 2 (Density ($\rho$) [kg/m³]): 1.2
  Line 3 (Kinematic Viscosity ($\nu$) [m²/s]): 1.5e-5
  Line 4 (Plate Length ($L$) [m]): 1.0
  Line 5 (Critical Reynolds Number ($Re_{cr}$)): 5e5
