Lecture 7 Flashcards
1
Q
iterative approach with minor losses
A
when calculating the new velocity must include minor losses
2
Q
pressure loss equation with minor losses
A
0.5densityC^2 * (friction factor *length/diameter +k)
3
Q
unused engine oil same as
A
SAE60 engine oil
4
Q
if possible what should be done first
A
calculate reynolds number to see if laminar or turbulent flow
5
Q
if type of fluid pressure head not stated assume
A
water
6
Q
pressure supplied by pump =
A
pressure losses
this does not mean that pressure straight after pump is equal pressure supplied by it
7
Q
work =
A
volume flow rate * pressure
8
Q
pressure supplied by pump =
A
change in pressure
