Chapter 14, Problem 14B.3ST

Interpretation Introduction

Interpretation:

Surface tension of the water is to be calculated.

Concept introduction:

Surface tension can be calculated by using following formula,

$\gamma =\frac{1}{2}\rho ghr$

$\begin{array}{l}\text{γ}\text{=}\text{surface}\text{tension}\\ \text{h}\text{=}\text{height}\\ \text{ρ}\text{= Mass}\text{density of the liquid}\\ \text{g}\text{=}\text{acceleration of free fall}\\ \text{r}\text{=}\text{radius}\end{array}$

Unit conversion

${\text{1 kg m s}}^{\text{-2}}\text{ = 1 N}$
