Jacob ( 1654-1705), John (1667-1748), James Bernoulli (1654-1705) and Daniel (1700-
1782), were all members of the same distinguished family of mathematicians and physics.
Bernoulliís Principle: Fluids in an area moving faster than the surrounding area possess less
pressure. Faster moving fluids equal less pressure. (Plate1A)
Fluids include liquids and gases. Air is a gas and is classified as a fluid. A relationship that
expresses the conservation of momentum in fluid flow. The usual form applies to the steady
in viscid flow of an incompressible fluid and can be obtained by integrating the Navier-
