🌈 Rainbow Mind map Pressure
Definition: Thrust per unit area
Factors affect: The magnitude of thrust acting on the surface and surface area on which thrust acts.
Units: S.I unit N / m²
CGS dyne/ cm²
1 N/ m² = 10 dyne / cm²
Pascal law: The pressure exerted by a Liquid at a depth is same in all directions.
Factors affecting liquid pressure: Height of a liquid column and density of a liquid
Atm: Atmospheric pressure is the thrust on a unit area of the earth surface due to air column above it.
1atm= 0.76 m of mercury column
= 1.03 x 10⁵ Pa
Here's a video representation for the same:
