Basic Definitions
Hydrostatics - the study of fluids at rest
Hydrodynamics or Hydraulics - the study of fluids in motion
Hydrostatics in History
Archimedes (the Siclian Scholar) had friend Hiero II (King of Syracuse)
Hiero had a wreath cast in pure gold but suspected the royal goldsmith of diluting the gold with silver.
How can he check the purity without damaging the wreath?
Hydraulics and Daniel Bernoulli
Bernoulli was trying to figure out how water flowed in pipes in 1725.
Doctors were trying to figure out how blood flowed in the veins.
Friction in Pipes Depends
Length of pipe
Internal diameter of the pipe
Average flow velocity of the pipe
The pipe material
And which friction equation you use..
State of Flow
Flow is governed by the effects of viscosity and gravity relative to the inertial effects of the flow
Flow can be laminar, turbulent or transitional
