Would appreciate if anyone could help me to find the mass flow rate from a 4" opening from a cylinder that is pressurized with air at 5 bar . The size of the cylinder is 24" and length is 600 mtr
 
There are two relevant FAQs



I think this is a fixed volume of air so what you have here is a transient issue as mass flow rate will start to fall from the start over time.

A 600 metre long 24" thing is not called a "cylinder", it's called a pipeline section...

But note that the flow will be sonic and a 4" opening will be very noisy and have very high velocity.

Can you give us a bit more here please?
