The time for pressure to build up

[Setareh7796]

Homework Statement

The volume and dimensions of the cylinder are given, and the air is supplied to the cylinder at 4 bar at room temperature.Is there a way to find out the time it takes for the air pressure in the cylinder to increase to 4 bar?

Homework Equations

The Attempt at a Solution

From my understanding, the flow rate should be given for me to calculate the time it takes, with knowing just the pressure and the volume of the cylinder, it is not possible to calculate the time it takes for pressure to build up.

What is the starting pressure?

What is the starting pressure?

From my understanding, the pressure in the cylinder will be at atmospheric pressure at the start.

 

[Chestermiller]

Are you saying that you know the flow rate, or does it change as a function of the pressure difference between the feed line and the interior of the tank?

 

[CWatters]

The flow rate depend on the pressure difference between pump and tank. As the pressure in the tank rises the pressure difference and flow rate falls. What happens as the pressure difference approaches zero?
