If dP = 0.5 mbar; V = 10 litres; and T = 20 degrees C;

Can someone show me the working (and answer) to determine the mass flow rate (m) using the ideal gas equation?

dP.V= (m/MA). RT

As far as I can tell ideal gas law is of no use when it comes to flow calculation, it describes static cases.

dP.V= (m/MA). RT

I was also confused by the MA

is it mass times acceleration?

[JB Mandengue]

MA is the atomic mass.

The situation the equation is considering is static. Gas is flowing in a pipe. To find the flow rate we close a valve to isolate a known volume and allow pressure to build up for a given length of time, and then use the ideal question to calculate the mass flow rate m.

So they are not using the convention of just capital M
