After completing your physics class, you are hired to help design a cigar lounge in a nightclub. The ventilation system is critical to this design, as it must circulate all the air in the room every 25 min to filter and purify it, respecting national health regulations. The ventilation ducts you will use have a square cross-section. If the lounge has a volume of 186 m3, and the fans pushing the air give you an airspeed of 3 m/s inside the ducts, what must be the minimum length of one side of the square duct? Assume that air can be treated as an incompressible fluid
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.
