Hello,
Im a student and I try to design a valve connected to a tank. However I have some troubles to define the phenomena. I have a pressurized tank with air at 100 bar and I would like to know the evolution of the flow rate through the opened valve. The valve outlet is at the atmospheric pressure. If I know the maximum flow rate i'll be able to define correctly my valve. I think I can use the relation PV=nRT but I don't really know how to link it with the flow rate. I used the isentropic expansion to determine the pressure and temperature in the tank but I 'm not sure that help. I only know the flow rate will decrease with the pressure of the tank.
Someone has an idea?
Thanks a lot.
