That's mean that you do'nt need to Download,
1. It generates a mathematical
formulations (equations) between
the variables:
The masse of volume and the flow of quantity of mouvement. :
The application do so automaticaly: ?
1. Select the variables liste at left ,
Select V: Vitesse (velocity) click then on ENTRER
2. From the right liste of variables selecte:
L : Dimension
"You can chang it's name to X (for example).".
Rau : Masse
Volumique.
DQM
: Débit de la quantité de mouvement: (The flow of quantity of
mouvement).
Click then on CALCULER (compute):
You obtain the needed relation
on the text zone below .
V~{[(DQM^0.5)]/[X*(Rau^0.5)]} The same as : 
B) One take now the
relation of the charge loses in tubes: 
In this equation we've 4
unknowns. So one has to define one of them, we pose 
Then we do ENTRER And CONTINUER LE CALCUL (continu
the computation)
to obtain the final following equation :
P~{[L*Rau*(V^2)]/[D]}
: 
2. Second function-
verification:
We'll verify the equation:
- At left we select
:
P : Pression- Contrainte
-Cisaillement (pressure Stress)
- At right we
select:
Rau :
Masse Volumique : we give the value of exponential 1
Then we
select:
V : Vitesse (velocity with exponential=2).
One click
on Vérifier : If we
obtain 7 Green OK(s) It mean's that our equation is correct.
