Fluids Chapter — Complete Concept Map

The map in words

  • FLUIDS
    • Thrust and Pressure
      • Thrust is perpendicular force
      • Pressure equals Force divided by Area
      • Unit is Pascal Pa
      • Small area means high pressure
      • Large area means low pressure
    • Pressure in Fluids
      • Acts in all directions
      • Formula P equals h rho g
      • Increases with depth
      • Depends on density
      • Does not depend on area
    • Atmospheric Pressure
      • Air column weight
      • 1 atm equals 1.013 times 10 to 5 Pa
      • 76 cm of mercury column
      • Barometer measures it
      • Decreases with altitude
    • Pascals Law
      • Pressure transmitted equally
      • Applies to incompressible fluids
      • Hydraulic Press application
      • Force Multiplier
      • F1 by A1 equals F2 by A2
    • Density and Relative Density
      • Density equals Mass by Volume
      • SI unit kg per m cubed
      • Relative Density is pure ratio
      • RD less than 1 means floats
      • RD more than 1 means sinks
    • Buoyancy and Archimedes
      • Upward force on immersed object
      • Upthrust equals weight displaced
      • Apparent weight loss
      • Archimedes Principle
      • Laws of Flotation
    • Instruments
      • Barometer for air pressure
      • Hydrometer for liquid density
      • Lactometer for milk purity
      • Pycnometer for relative density
