Two flasks (which we will refer to as flask 1 and flask 2) are connected to each other by a U-shaped tube filled with an oil having a density of 0.907 g ml ¹. The oil level in the arm connected to flask 2 is 17.52 cm higher than in the arm connected to flask 1. Flask 1 is also connected to an open-end mercury manometer. The mercury level in the arm open to the atmosphere is 11.90 cm higher than the level in the arm connected to flask 1. The atmospheric pressure is 0.745 atm.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
