Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

You have been moved into the laboratory for the fluid testing for hydraulic devices, where your job is to illustrate the results of a viscosity test on a Newtonian fluid at various temperatures and explain discrepancies after completing the following given data-sheet in Table A.
