Explanation:
air pressure:-Some common use of air pressure in daily life is inflating tires, playing musical wind instruments, drinking through straw, flushing toilet, drawing water from well, operating barometer, blowing up balloon, breathing, maintaining body shape especially abdomen
liquid pressure :-When we spray deo or paint through a bottle.
we use in syringes.
when we open a bottle of coke.
when we open the tap we find the water gushin out through great pressure.
its also used in basic hydraulic system. 4.2. 68 votes. 68 votes. 139. bijjam. Virtuoso.

Applications of Pressure in Daily Life
Application of atmospheric pressure or just air pressure refers to the numerous activities that we do or observe every day without even realising that there is an iota of pressure getting into the picture.
This is the same air pressure which is equivalent to 15 lbs per square inch at sea level and helps keep things around us the way they are.
We survive in this high pressure condition because we have evolved and managed our body functions withstand this amount of high pressure.
Whatever changes and activities we see around us are from the fact that these are mainly accomplished at sea level and that they are mostly spontaneous it always tries to maintain equilibrium between different physical systems.
Any changes either from the place of activity or on account of physical systems might cause change in pressure leading to the impairment or dysfunction of the system.
Let’s take a look at the different application of air pressure that we fail to note but are omnipresent.
(a) When we breathe the atmospheric pressure of 15 lbs at sea level causes the oxygen to pass through the semi permeable membrane easily. If the same activity is carried out in higher altitudes might cause hypoxia or deprivation of oxygen due to lower air atmospheric pressure.
(b) The ink dropper that we use almost on a daily basis actually works on the air pressure principle. As soon we create a low pressure by removing the air inside the bulb, the ink flows in to fill in the void.
(c) When a jet liner flies above 10000 feet the cabin pressurization is maintained by pumping compressed air into it to compensate the low pressure outside.
If not done these might lead to bleeding from nose and ears as the high blood pressure inside the blood vessels compared to low pressure would make them swell and burst open.
(d) The working of plungers that we use in sink revolves around the same principle of having lower pressure inside compared to the air pressure outside and the suction is nothing but actually a difference in air pressures.
(e) An aeroplane would take off from the ground based completely on the fact that when we cause the air to move we lessen the air pressure in the immediate surrounding and that helps in lifting the aeroplane.
(f) The cleaning vacuum used in homes are again working on the same principle of lower pressure created inside the machine causing it to suck everything inside including dust particles.
(g) Suction pumps used in village areas works on the same principle of creating low pressure inside the cylinder when we lift the piston and that causes the atmospheric pressure to push up the water to the surface.
