1. The problem statement, all variables and given/known data
Calculate the time required to pressurise a tank to P_t, given volume, pump delivery rate (cfm), starting pressure, and end pressure.
2. Relevant equations
Unknown. I don't have access to a fluid mechanics textbook at the moment, unfortunately, so I don't know where to start. If anyone can provide a link to an online resource or a relevant standard, I would be grateful.
3. The attempt at a solution
I have been forwarded the following equation:
[tex] t = \frac{volume*\Delta{P}}{7.48*cfm*P_{atm}}[\tex]
Does anyone recognise this, or know where it is from? The units are all imperial.
