A Pilot unit of a closed loop gas (CLS) mixing and distribution system for the INO project was designed and is being operated with (1.8 x 1.9) m^2 glass RPCs (Resistive Plate Chamber). The performance of an RPC depends on the quality and quantity of gas mixture being used, a number of studies on controlling the flow and optimization of the gas mixture is being carried out. In this paper the effect of capillary as a dynamic impedance element on the differential pressure across RPC detector in a closed loop gas system is being highlighted. The flow versus the pressure variation with different types of capillaries and also with different types of gasses that are being used in an RPC is presented. An attempt is also made to measure the transient time of the gas flow through the capillary.
