| Abstract: | Conclusions A scheme of a laboratory set-up for measuring the gas-dynamic resistance of hollow fibre channels over a wide range of temperatures and pressures has been described.A procedure for performing experiments and the results of experimental measurements of the flow rate of nitrogen, ammonia, argon, hydrogen, helium, and methane through the channels of polypropylene fibres from 20 to 0.2 m in length at 293°K and a pressure drop from 0.098 to 2.124 MPa have been presented.It has been found that the flow rate of the investigated gases increases regularly on increasing the pressure drop and decreases with increase in the length of the hollow fibre specimen. For hydrogen, helium, nitrogen, and argon, under otherwise equal conditions, flow rate decreases with increase in molecular weight of the gas. For ammonia and methane, a deviation from this relationship is observed, since the flow rate of these gases exceeds that of helium.Translated from Khimicheskie Volokna, No. 6, pp. 13–14, November–December, 1985. |
