A lactometer is a specialized hydrometer used measure the relative density and purity of milk. A lactometer has graduations from 1 3 (top-bottom) between the uppermost marking of W representing the density of water and the lowermost marking of M representing the density of pure milk.
A lactometer is a specialized hydrometer used measure the relative density and purity of milk. ... If the milk is pure the readings will be close to 1 and if the amount of water in the milk increases then the markings will be close to 3.
Explanation: In order to calculate the electric flux through the any surface we have to take into account the scalar product between the electric field vector and the normal vector to the surface.
So we have:
ФE= E*A= 1.33 * 10^4*0.0518* cos (33.2°)= 576.48 N*m^2/C
