  1. Density (ρ)
    Image Upload

    [SI units: kg/m3]
  2. Specific Gravity
    Specific Gravity = Image Upload  = Image Upload     [No Units]

    ρwater = 103 kg/m3
  3. Weight (W)
    W = ρgV
  4. Pressure:
    a scalar quantity defined as force per unit area: 

    Image Upload       [SI Units: Pascal = N/m2]

  5. Pressure of a Static Fluid:
    For static fluids of uniform density in a sealed vessel, pressure:

    P = ρgh
  6. Absolute Pressure
    in a fluid due to gravity somewhere below the surface is given by the equation

    P = P0 + ρgh

    Absolute pressure is zero-referenced against a perfect vacuum, so it is equal to gauge pressure plus atmospheric pressure.
  7. Gauge Pressure
    Gauge pressure is zero-referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. Negative signs are usually omitted.

    Pg = Pabs - Penvironment
  8. Continuity Equation
    V1A1 = V2A2
  9. Bernoulli's Equation:
    P + Image Uploadρv2 + ρgh = constant
  10. Archimedes's Principle
    difference between object's weight in air and weight in fluid:

    Fbuoyant = ρfluidgVsubmerged
