Question

A dimensionally consistent relation for the volume V of a liquid of coefficient of viscosity $\eta$ flowing per second through a tube of radius r and length l and having a pressure difference P across its end, is

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Formula for viscosity $\eta =\frac{\pi P{\gamma }^4}{8Vl}\Rightarrow$ V = $\frac{\pi P{\gamma }^4}{8\eta l}$
