Calculator : Specific Speed & Cordier Diagram
Category   : Tools

Files Included:
  - specific_speed.f90 (Fortran 90/2008 Source Code)
  - input.txt (Pre-configured Sample Input)

-------------------------------------------------------------------------
1. How to Compile
-------------------------------------------------------------------------
Make sure you have GNU Fortran (gfortran) or Intel Fortran (ifort) installed.
Run the following compilation command in your terminal:

  gfortran -O3 specific_speed.f90 -o specific_speed

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

  specific_speed < input.txt

-------------------------------------------------------------------------
3. Input Parameter Sequence
-------------------------------------------------------------------------
Machine type (1=Centrifugal Pump, 2=Axial Pump, 3=Centrifugal Fan, 4=Axial Fan, 5=Radial Turbine, 6=Axial Turbine)
Volumetric flow rate Q [m3/s]
Head H [m] (or pressure Pa for fans)
