Step Responses of Blocked Pneumatic Lines.

摘要

Pressure step responses for rigid pneumatic lines blocked at one end were recorded for lines from 0.067to 0.750inches in inner diameter, 2.0to 80.0feet long. Each line size was subjected to a series of positive-going (vacuum) and negative-going (pressure) steps of plus or minus 0.5, 1.0, 2.0, 4.0, 6.0, 8.0and 10.0psig. The final steady-state pressure in the lines was ambient pressure, 11.3psia. Selected average normalized step responses are shown in graphical form;complete results are given in tabular form. (Author)
