below shows a horizontal pipe with a varying cross section. A liquid with a density of 1.65 g/cm3 flows from left to right in the pipe, from larger to smaller cross section. The left side's cross-sectional area is 10.0 cm2, and while in this side, the speed of the liquid is 2.48 m/s, and the pressure is 1.20 ✕ 105 Pa. The right side's cross sectional-area is 3.50 cm2 What is the speed (in m/s) of the liquid in the right side (the smaller section)? (Enter your answer to at least three significant figures.) What is the pressure (in Pa) of the liquid in the right side (the smaller section)?
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.
