An hydraulic car lift at the repair shop except the area of the large piston is 150 times that of the small piston. How many N of force needs to be applied to the small piston to exactly balance a 2500 kg car? In the example above, what distance must the small piston move in order to raise the car 5 m? A balloon is filled with 1000 cm3 of a gas weighing 1000 g. Will it rise or fall when it is released? For the balloon in the above question, whether your answer is rise or fall, why did you answer it that way?
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.
