Calculator : Specific Speed & Cordier Diagram
Category   : Tools

Files Included:
  - specific_speed.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 -O3 specific_speed.f90 -o specific_speed

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

  specific_speed < 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 (Machine type (1=Centrifugal Pump, 2=Axial Pump, 3=Centrifugal Fan, 4=Axial Fan, 5=Radial Turbine, 6=Axial Turbine)): 1
  Line 2 (Volumetric flow rate Q [m3/s]): 0.1
  Line 3 (Head H [m] (or pressure Pa for fans)): 30.0
  Line 4 (Rotation speed N [rpm]): 1450.0
  Line 5 (Machine diameter D [m] (0=estimate using Cordier correlation)): 0.0
