Viscosity of water in comparison to mercury is
Answer & Solution
Correct Answer:
Option
B
Viscosity of water in comparison to mercury is Lower.
Viscosity: It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction.
Mercury dynamic viscosity at temperature 300K is 1.53
Water dynamic viscosity at temperature 300K is 0.89

LoginFor same shear stress the velocity gradient of water is higher than velocity gradient of mercury .
Also, viscosity is inversely proportional to velocity gradient.
So, we can say that viscosity of water is lower than viscosity of mercury.
