It's based on Chen ecuation, it's runs in basic not in cplua, I did this program (it's a very easy program).

The program you're saying is another way to calculate the same thing, but this one is more rigorous. Thanks anyway! If you know anything about this program please contact me

Q: volume/time (caudal)
S: pipe section
u: viscosity (kg/m/s)
uc: cinematic viscosity (m^2/s). uc=u/ro
e: absolute rugosity
Your variables are: Q,D,e,uc
e/D: relative rugosity (one of my variables)
Re=V?D?ro/u=V?D/uc, but first you need calculate V
If Q=V?S=V?Pi?D^2/4 -> V=Q?4/Pi/D^2 put the velocity in the up line and you will calculate the reynolds number, that is the another one of my varibles
Is the same, if you want, you can modify my program in order to input your variables. The Chen ecuation is enough accurate, if you prefer Colebrooke you will have to make it with cplua, I think that this ecuation needs a iterative method.

To pass the program from pc to class pad you need classpad manager, it's in the cd that comes with the classpad's box.
Are you mechanical engineer or chemical engineer?
