A) Bernoulli theorem
B) Archimedes' principle
C) Poiseuille's equation
D) Stoke's law
Correct Answer: C
Solution :
Poiseuille's formula gives the volume of a liquid flowing out per 'second through a horizontal capillary tube of length 1, radius r, under a pressure difference? applied across its ends. \[\frac{{{h}_{1}}}{{{h}_{2}}}=\frac{{{u}^{2}}}{2g}\times \frac{8g}{{{u}^{2}}}\Rightarrow \frac{{{h}_{1}}}{{{h}_{2}}}=\frac{4}{1}\]
