ICSE Class 9 Physics Transmission of pressure in liquids
It is a scientific instrument used to measure atmospheric pressure, also called barometric pressure.
Particles of fluid always move from an area of higher pressure to an area of lower pressure. Fluids have the ability to transmit pressure.
The decrease in atmospheric pressure can cause psychological and physical discomfort for people and animals.So, air cabins are artificially pressurized
1 atm = 101325 Pa
Pascal's law is a principle in fluid mechanics that applies to transfer of pressure in liquids,
Pressure on a liquid depends on only 3 factors.
Pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container.
Units of pressure-Pascal
Atmospheric pressure is a measure of absolute pressure. Gauge pressure is the additional pressure in a system,relative to the atmospheric pressure
The circulatory system relies on pressure differences in circulating blood, oxygen, nutrients, and waste products throughout the body. Respiration is a result of pressure differences between the thoracic cavity, the lungs, and the environment, regulated by the movement of the diaphragm.
