What is the equation of continuity dealing with
Mass flow of air
What is Bernoulli’s theorem dealing with?
Conservation of Energy
Name x3 air flow
Laminar, Turbulent and Vortex
What do vortexes lose energy to
the surrounding air
If we take air to be an ideal fluid what will it not have
No Viscosity and incompressible
Mass flow equation =
AVp (row)
If we look at change in flow rate in a ventrui as area decreases what happens to V?
Increases
What is Bernoulli’s theorem in an equation
Pt = Pd + Ps
Streamlines =
Direction of a small quantity of flowing air which cannot be crossed
Stream tube =
A volume of air bounded by steamlines
Which letter is dynamic pressure expressed as
q (1/2 P V ^2)
In a convergent duct what happens to Dynamic Px and Static Px
Dynamic increases and Static decreases
