Problem 2.246

Making use of Poiseuille's equation \((1.7 \mathrm{~d}),\) find the mass \( \mu \) of gas flowing per unit time through the pipe of length \(l\) and radius \(a\) if constant pressures \(p_{1}\) and \(p_{2}\) are maintained at its ends.

\mu=\frac{\pi a^{4} M}{16 \eta R T} \frac{\left|p_{2}^{2}-p_{1}^{2}\right|}{l}
