Explain how to compute the flow time necessary for backing gas to purge a pipe of air.
What will be an ideal response?
First, estimate the interior volume of the pipe. Second, convert the flow rate into cubic inches per minute (cm3/min). Third, to get the time required divide the estimated volume by the flow rate. Last, round any fractions of minutes off to the next highest minute.
