Estimate the effect of the magnetic field in the conditions of the previous problem, if a 30% solution of sulphuric acid flows in the pipe. The conductivity of the solution is `74ohm^(-1).m^(-1)`.

Answer

It will not.

Explanation

`Re=(1.02xx10^(3)xx5xx10^(-2)xx0.2)/(2.44xx10^(-3))=4200gt2300`
`N=(73.9xx0.36xx5xx10^(-2))/(1.02xx10^(3)xx0.2)=6.5xx10^(-3)ltlt1`.
