Question

what is viscosity? in marks

Answer 1

ANSWER


VISCOSITY


it is an state of being thick, sticky, and semi-fluid in consistency, due to internal friction.


resistance of a fluid to a change in shape, or movement of neighbouring portions relative to one another. 


EXAMPLE

syrup has a higher viscosity than water.

Answer 2

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.

The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

The coefficient of viscosity is a measure of resistance to flow of the fluid. Dynamic viscosity μ is used in Darcy's law to calculate the rate of fluid flow in porous media. The relationship between viscosity and flow rate defines the rheology of the fluid.
