I have a pneumatic filled storage tank with a scrubber in the vent line to atmosphere. Once filled, for a brief time I will have air pressure on the tank until closing the air valve. I need to calculate this tank pressure to determine the fill pressure so as not to exceed the allowable tank pressure. Searcing the Crane book for system resitance to determine air mass flow rate. Fill line size and vent line size are diferent. How should I determine max. tank pressure with known fill pressure and vent to atmosphere pressure knowing the resistentances? Your thoughts would be appreciated.
Thanks,
Bonkers
