Hello All, I was given a problem today that I could use some guidance on. I have a compressed air pipe flowing into a container. This container has a pressure of 5 psi while the pipe has a pressure of 90 psi. There is a valve that controls when the air is released into the vessel and only allows three seconds worth of compressed air to enter the vessel at a time. My question is what is the volumetric flow rate into the tank during these intervals in Gal/second. The pipe diameter is 1.5" and the compressed air temperature is 70 °F. Any equations or guidance would be helpful, if there's something that I may have left out just post and Ill try to answer as soon as possible. I may be able to collect data to determine other parameters also. Thanks.
