Lecture 7

Question 1

iterative approach with minor losses

Answer 1

when calculating the new velocity must include minor losses

Question 2

pressure loss equation with minor losses

Answer 2

0.5densityC^2 * (friction factor *length/diameter +k)

Question 3

unused engine oil same as

Answer 3

SAE60 engine oil

Question 4

if possible what should be done first

Answer 4

calculate reynolds number to see if laminar or turbulent flow

Question 5

if type of fluid pressure head not stated assume

Answer 5

water

Question 6

pressure supplied by pump =

Answer 6

pressure losses

this does not mean that pressure straight after pump is equal pressure supplied by it

Question 7

work =

Answer 7

volume flow rate * pressure

Question 8

pressure supplied by pump =

Answer 8

change in pressure
