    1. The problem statement, all variables and given/known data
    Hello, I have really hard time to express the gas law PV=nRT to PQ=ṁRT where Q is volumetric flow rate and ṁ- mass flow rate.
    Is it possible ?
    Teacher told me, it is ...

    2. Relevant equations

    3. The attempt at a solution

    So what are the relevant equations? How can you express ##Q## and ##\dot{m}##?

    What have you tried?

    Is it gas flow in a pipe, or is it some other geometry?
