  Single gap glass Resistive Plate Chambers with areas of 17x17 cm2 and 30x30
cm2 are constructed in the Particle Detector Laboratory in the Sahand
University of Technology. Simulation of the gas flow through the chambers is
performed using commercial ANSYS-Fluent package. We have shown that flow rate
has a linear relation with the pressure of the gas inside the chamber. We have
also investigated the dependence of the gas pressure on the length of the hose
connected to the outlet of the chamber and shown that it varies linearly.
Simulation results are compared with experimentally measured values.
