Pressure in Fluids

PRESSURE= THRUST/AREA
1. Units Of Pressure
  1. SI Unit : pascal (Pa)
  2. Gravitational Unit: kilogram force per square metre (kgf/m2)
  3. Meteorological Unit: bar
Mathematical Expression
1. P=h.d.g
  1. h=Height of the liquid column
  2. d=density of liquid
  3. g=acceleration due to gravity
Laws of Liquid Pressure
1. Experimental Explanation
  1. To prove that pressure at a point inside the liquid increases with the increase in the density of fluid.
  2. To prove that a liquid seeds its own level.
2. Curiosity Quotient
