Understanding Young's Modulus
Young's modulus is a fundamental property of materials that measures their stiffness or resistance to deformation when subjected to tensile or compressive stress. It is defined as the ratio of stress (force per unit area) to strain (relative deformation) in the elastic region of a material’s stress-strain curve.

Pk Academy answered • yesterday |
In space above mercury column in barometer, ideally perfect vaccum is expected. But due to evaporation of mercury , the pressure in that space is equal to vapour pressure of mercury [nearly 0.2 Pa (abs)] . As absolute pressure in that space is less than atmospheric pressure, gauge pressure is negative.

Intravenous infusions are usually driven by gravity, by hanging the fluid bottle at sufficient height to counteract the blood pressure in the vein and to force the fluid into the body. The higher the bottle is raised, the higher the flow rate of the fluid will be. The density of the fluid is 1020 kg/m3.
If it is observed that the fluid and the blood pressures balance each other when the bottle is 1.2 m above the arm level, determine the gauge pressure of the blood in kPa.
