Description

Syringe with screw-piston mounted on base.This
device enables you to accurately vary and maintain the pressure.A
retractable safety device enables you to limit the pistons' stroke, and thus the
pressure, in order to protect the manometer which will be connected to the
system. The 3-way-valve has 2 functions : firstly, it enables to
adjust the air volume to be introduced in the syringe, then to cut the
communication with the outside by introducing the manometer in the pressure circuit.

En utilisant un pressiomètre Initio® 2 et une console d'acquisition munie d'une entrée voltmètre, il est possible d'informatiser le TP.

Courbe de la pression en fonction du volume :

En utilisant les outils de calcul du logiciel Atelier Scientifique, mettre cette courbe sous la forme V = f(1/P).
En mettant l'équation des gaz parfaits P(Vtuyau + Vseringue) = NRT sous la forme V =a/p - b, faire une modélisation linéaire du relevé précédent pour déterminer a et b.
a = NRT et b le volume du tuyau
