Hello. I want help in a problem I am facing.
A testbox of known area has to be pressurized with air. I want to find the time needed to fill the box with certain pressure (in psi). Can anyone help me find a way to it.

According to the reference provided by you, the factor k depends on natural logarithms. But the initial pressure in my case is assed to be zero. Taking zero as initial pressure, I don't think the equation works.
