Mechanical Properties of Fluids

Question: A liquid is coming out from a vertical tube. The relation between the weight of the drop $W$, surface tension of the liquid $T$ and radius of the tube $r$ is given by, if the angle of contact is zero

1) $W=\pi {{r}^{2}}T$

2) $W=2\pi rT$

3) $W=2{{r}^{2}}\pi T$

4) $W=\frac{3}{4}\pi {{r}^{3}}T$
