A liquid drop of diameter 2 mm and surface tension 70 dy `cm^(-1)` is sprayed into 1000 identical small droplets. Calculate the work done in the process.

Text Solution

Verified by Experts

Number of drops n = 1000, diameter of drop d = 2mm, radius of drop r = 1mm = `10^(-1)cm`
surface tension T = 70 dyne `cm^(-1)`, work done to spray the large drop into small drops W = `4pir^(2)T(n^(1//3)-1)`
`rArrW=4xx22/7xx(10^(-1))^(2)xx70[(1000)^(1//3)-1]`
`rArrW=4xx22xx10^(-2)xx10xx9rArrW=79.2"ergs".=7.9xx10^(-6)J`.
