Thermodynamic Open System Question Regarding Air Reservoirs
Hey Guys, new member here looking for a little help. I'm a freelance Product Designer that has very little experience with Thermodynamics, and has a client that expects this is a lot easier than it really is!
What I'm working with is effectively the same things you would find in your average workshop compressor.
Please see the image below:

So I have a 20L container, it has a pressure switch which allows air to enter when the pressure is below 1.5 Bar, and stops the air entering when it reaches 3 Bar. Air is exiting the container at a constant flow rate; it is being regulated so that it provides a constant 1.4 Bar pressure at 48.3 L/min.
When the pressure in the container reaches 1.5 Bar, I want to raise the pressure of the container back up to 3 Bar in 60 seconds.
What pressure and flow rate is required coming in to the container to achieve this?
I feel as though it should be not be difficult to work out, but I've tried reading up on the first law of thermodynamics, open system and steady flow processes, but it has not helped!
If anyone has a clue, I would be very grateful!
