Bernoulli

Bernoulli

1. The Bernoulli Equation can be considered to be a statement of the conservation of energy principle appropriate for flowing fluids.

2. Particles might undergo changes that affect energy type

   • change in v, kinetic energy
   • change in elevation, gravitational potential energy
   • change in pressure, Mechanical potential energy

3. B.E is true

   • flow is steady
   • fluid is inviscid
   • density is constant
   • no frictional losses
   • equation relates two points along a single streamline
   • no shaft work or heat transfer

4. Head Form

   • pressure head + velocity head + elevation head = constant

5. Pressure Form

   • static pressure + dynamic pressure + hydrostaic pressure = consatnt
