Presentation Transcript

  1. Pressure

  2. Pressure P=F/A P=Pressure (Pa) F=Force (N) A=Area (m2) • Magnitude of the force on a surface per unit area

  3. Pascal’s principle • Applied pressure is transmitted equally throughout a fluid.

  4. Hydraulic lift • A small F1 applied to a small A1 is the same as a large F2 applied to a large A2

  5. Pressure varies with depth in a fluid • P= P0+ρgh • P= Absolute Pressure(Pa) • P0=atmospheric pressure (Pa) • ρ=density kg/m3 • g= gravity m/s2 • h=height (depth) m
