Bernoulli

Bernoulli

The Bernoulli Equation can be considered to be a statement of the conservation of energy principle appropriate for flowing fluids.
Particles might undergo changes that affect energy type
1. change in v, kinetic energy
2. change in elevation, gravitational potential energy
3. change in pressure, Mechanical potential energy
B.E is true
1. flow is steady
2. fluid is inviscid
3. density is constant
4. no frictional losses
5. equation relates two points along a single streamline
6. no shaft work or heat transfer
Head Form
1. pressure head + velocity head + elevation head = constant
Pressure Form
1. static pressure + dynamic pressure + hydrostaic pressure = consatnt
