Fluid Mechanics Viscosity Question 47
Question: Two capillaries made of the same material with radii $ r_{1}=1mm $ and $ r_{2}=2mm $ . The rise of the liquid in one capillary ($ r_{1}=mm $ ) is 30 cm, then the rise in the other will be [MP PET 1991]
Options:
A) 7.5 cm
B) 60 cm
C) 15 cm
D) 120 cm
Show Answer
Answer:
Correct Answer: C
Solution:
$ \frac{h_{2}}{h_{1}}=\frac{r_{1}}{r_{2}}=\frac{1}{2}\Rightarrow h_{2}=\frac{30}{2}=15cm $
