ICSE Class 9 Physics Transmission of pressure in liquids
|
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.
Hydrostatic pressure is the pressure of fluid caused by the force of gravity. Blood pressure is the hydrostatic pressure of blood on the blood vessel walls.
Pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container.
Pressure on a liquid depends on only 3 factors.
The decrease in atmospheric pressure can cause psychological and physical discomfort for people and animals.So, air cabins are artificially pressurized
The total pressure at any point within an incompressible is the sum of the applied pressure at any point in that fluid and the hydrostatic pressure change,due to a difference in height within that fluid.
It is a scientific instrument used to measure atmospheric pressure, also called barometric pressure.
Pascal's law is a principle in fluid mechanics that applies to transfer of pressure in liquids,
