Determination of Pressure Response Times for Gaseous Flow in a Tube
Abstract
The motivation for determining the response time for a pressure regulator to adjust the pressure at an area of interest located at the end of a long tube may be due to several reasons. One of these is the possibility that the regulator cannot be conveniently controlled from a more desirable position closer to the area of interest. Another reason to place to place the regulator a long distance from the area of interest might be to avoid high pressure lines over a prolonged distance. Consider the system shown in Figure 1, which is the proposed propulsion system for a microgravity experiment located in the Shuttle car bay. The regulator is controlled electronically so the ability to reduce the amount of electrical wiring will increase system reliability. Furthermore, Shuttle safety requirements demand that high pressure lines be tested for space worthiness, thus placement of the regulator close to the propellant source may eliminate the presence of these high pressure lines.
