Shear stress develop in water is more than mercury. As viscosity is directly proportional to shear stress.
So water has higher viscous property than Hg.
So water has higher viscous property than Hg.

Kinematic viscosity of water is more than mercury, but Dynamic viscosity of water is less than mercury.

Viscosity of water is higher than mercury.

The kinematic viscosity is the dynamic viscosity divided by the density.
Mercury is a lot denser than water, so its kinematic viscosity is lower than the kinematic viscosity of water. But that's just because mercury is very dense. But The dynamic viscosity of mercury is greater than water.

Decreasing order of viscosity.
Hg>water >petrol >air.
Hg>water >petrol >air.

Dynamic viscosity of mercury is higher then water. But kinematic viscosity (dynamic viscosity/ density). So kinematic viscosity of mercury is less than water.

Viscosity of mercury is lesser than of water, because shear stress developed in water is more than mercury, this is taken from the relation viscosity is directly proportional to the shear stress and inversely proportional to velocity gradient.

It is only true for kinematic viscosity. Because mercury has large density than water.

Water viscosity is less than mercury. Please correct it.
