Question

Differentiate between relative and absolute viscosities

Answer 1

$\huge\mathcal{\fcolorbox{lime}{black}{\orange{Answer}}}$

Absolute or dynamic viscosity is the internal resistance that a fluid faces against flowing freely. ... Relative viscosity is the ratio of viscosity of a solution containing a solute to the viscosity of the pure solvent.

Answer 2

Answer:

Absolute or dynamic viscosity is the internal resistance that a fluid faces against flowing freely. ... Relative viscosity is the ratio of viscosity of a solution containing a solute to the viscosity of the pure solvent.

Explanation:

It is the viscosity of a fluid in which a tangential force of 1 dyne per square centimetre maintains a difference in velocity of 1 centimetre per second between two parallel planes 1 centimetre apart. ... One poiseuille is 10 poise or 1000 cP, while 1 cP = 1 mPa·s (one millipascal-second).
