Calculating time required to pressurize compressed air tank

  1. Dec 12, 2014 #1

    I searched as best I could but could not find a direct answer to my question; I've seen similar questions but without the required data to be able to make the calculation. I thought this would be a simple calculation to find but apparently not.

    Compressed air source is 4.46cfm @ 93psi - assume this stays constant
    Tank volume is 636 cubic feet
    Initial tank pressure is 0psig
    Final tank pressure is 15psig

    I need to calculate the time required to pressurize this 636cf tank from 0psig to 15psig when the supply of compressed air is 4.46cfm @ 93psi.

    If anyone could provide me with the equation to make this calculation, I would be grateful.
