The article will cover essential aspects of fluid statics and pressure forces applied to the fluid. The article will start with the absolute pressure gauge and the variation of pressure with depth in different gravitational field manometers and barometers, respectively. Then I will explain the forces that deal with fluids, such as hydrostatic force, buoyant force, etc. So, dear friends, without wasting any time, let’s start. Pressure The definition of pressure according to fluid mechanics is as follows: Pressure is the normal force applied by a fluid per unit area. Unit of Pressure The units of pressure Pascal is too small to deal with in practical cases. For instance, Kilopascal: 1kPa=103Pa Mega Pascal: 1MPa=106Pa The three common pressure units used are standard atmosphere bar and kilogr ...
