Two capillary tubes of the same length but different radii r1 and r2 are fitted in parallel to the bottom of a vessel. The pressure head is p. What should be the radius of a single tube that can replace the two tubes so that the rate of flow is same as before ?
- r1 + r2
- \(\frac{\mathrm{r}_{1} \mathrm{r}_{1}}{\mathrm{r}_{1}+\mathrm{r}_{2}}\)
- \(\frac{r_{1}+r_{2}}{2}\)
- None of these
Answer
(D) None of these
