Concept explainers

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.

0 Jorge wishes to observe the progress of his vacuum pump in evacuating a tall bell jar for the purpose of demonstrating that sound waves do not travel in a vacuum. So, Jorge places a mercury barometer inside the bell jar and follows the height of the mercury column as the pump chugs away. The density of mercury is 1.36 × 104 kg/m³ and the standard atmospheric pressure is 1.01 × 105 Pa. The acceleration g due to gravity is 9.81 m/s². When he observes a height of 7.89 mm of mercury, what fraction of atmospheric pressure, expressed as a percentage P, has Jorge achieved in his bell jar? P = %

A light spring of constant k = 80.0 N/m is attached vertically to a table (figure (a)). A 2.30-g balloon is filled with helium (density = 0.179 kg/m3) to a volume of 2.50 m3 and is then connected to the spring, causing the spring to stretch as shown in figure (b). Determine the extension distance L when the balloon is in equilibrium. (The density of air is 1.29 kg/m3.) m
The lower section of a constricted pipe has a diameter of 8 cm. The upper section of the pipe, located 0.1 m above the lower section, has a diameter of 3 cm. The pressure at the lower section is 2.1 ×× 104 Pa, while the pressure in the upper section is 1 ×× 104 Pa. Assuming water moves through the pipe in a steady flow, calculate the speed (in m s-1) of the flow in the lower section. The density of water is 1000 kg m-3.
