Q. 10 VSA

Streamline flow is more likely for liquids with
A. high density.

B. high viscosity.

C. low density.

D. low viscosity

Answer :

Critical velocity is the velocity of the liquid up to which liquid can be streamlined and above which it is turbulent.


It is related to coefficient of viscosity and density as,



Hence, for a streamline flow the critical velocity should be high and hence density should be low and coefficient of viscosity should be high. High coefficient of viscosity indicates high viscosity of a liquid.
