5. A human being has an average venous blood pressure of 12 mm Hg (Hg = mercury). The density of Hg (mercury) is 13,530 kg/m3. How high does a saline bag have to be raised to just barely enable the flow (that is, the pressure of the saline at the needle is equal to that of the blood in the vein) of saline through a line and needle inserted into a person's vein? The density of saline is 1020 kg/m3.

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.
