Pressure
- Thrust
- measured in dynes in the CGS system and newton or N in the SI system
- vector quantity
- scalar quantity
- solids exert pressure on another surface on account of its weight
- measured using Simple Barometer,Fortin's Barometer,Aneroid Barometer
- Thrust/Area or F/A
- Pressure in Fluids
- All liquids and gases
- fluid enclosed in a vessel exerts pressure at all points and in all directions
- P=hPg
- h is height or depth
- P is density
- g is acceleration due to gravity
- pressure in Fluids is directly proportional to hPg
- Hydraulic Press
- Based on Pascal's Law
- MA=(radius of larger piston)^2/(radius of smaller piston)^2
- gas is measured using Gas Manometer or Pressure Gauge
