The pressure of confined air is p. If the atmospheric pressure is P, then :-

The pressure exerted by air is called atmospheric pressure.

Figure shows a crude type of atomizer. is compressed, air flows swiftly through tube BC causing a reduced pressure in the particles of the vertical to Liquid rises in the tube, enters BC and is sprayed out. if the pressure in the bulb is P_(a) + P , where P is the gauge pressure and P_(a) is the atmospheric pressure, v is the speed of air in BC , find how large would v need to be to cause the liquid to rise to BC . Density of air = 1.3 kg//m^(3) .

What is atmospheric pressure of air?

A source of sound placed at the open end of a resonance column sends an acoustic wave of pressure amplitude P_(0) inside the tube. If the atmospheric pressure is P_(A) , then the ratio of maximum and minimum pressure at the closed end of the tube will be

Air moves into the lungs when atmospheric pressure is
