Two capillary tubes of same length but radii r1 ,r2 are fitted in parallel to a bottom of a vessel. The pressure head is p. What should be the radius of single tube that can replace the two tubes so that the rate of flow is same as before r2 are fitted in parallel to a bottom of a vessel. The pressure head is p.
