Fluid Flow Flashcards
Give the equation for force.
F=m.(c2-c1)
Give an equation for Ftotal
Ftotal=Fpressure+Fresultant
Give some assumptions for pipe flow
Ideal flow, incompressible fluid, steady flow
Give an equation for power
P=Hgm.
When representing the fluid power graphically what does a lower speed do to the gradient if the line?
Makes it less steep. So wider pipes have less flow so a less steep line
When representing the fluid power graphically, what is the dotted line?
The hydraulic line
When representing the fluid power graphically, what is the solid line?
The total head
When representing the fluid power graphically, what is the difference between the two lines?
The dynamic head
When representing the fluid power graphically, what do the vertical lines show?
Vertical up is gain of energy (e.g. From a pump) wertical line down represents a fittings loss
When representing the fluid power graphically, what does the dotted line come to at the end tank?
The waterline of the tank
What is Mach number and give the equation.
The non dimensional velocity relative to the speed of sound.
M=C/a where a is the speed of sound
In a convergent divergent nozzle what is M in the centre. (The thin part)
