Answer:
The correct answer is head varies directly with square of velocity of flow
Explanation:
The head loss in a pipe as given by Darcy Weisebach equation is
where
'f' is friction factor whose value depends on the nature of flow (Laminar/turbulent)
'L' is the length of the section in which the head loss is calculated
'v' is the velocity of the flow
'D' is the diameter of the duct
Thus we can see that the head loss varies with square of velocity of the fluid.
Answer:
Head loss in turbulent flow is varying as square of velocity.
Explanation:
As we know that head loss in turbulent flow given as
Where
F is the friction factor.
L is the length of pipe
V is the flow velocity
D is the diameter of pipe.
So from above equation we can say that
It means that head loss in turbulent flow is varying as square of velocity.
We know that loss in flow are of two types
1.Major loss :Due to surface property of pipe
2.Minor loss :Due to change in momentum of fluid.
Answer:
47.3 ml
Explanation:
The graduated cylinder is shown in the image attached.
Now we have to take a good look at the cylinder, the lines between 45 and 50 are 46, 47, 48 and 49. Even though the points in between two lines weren't graduated but we can intelligently guess the correct volume by observing the upper meniscus of the liquid. Hence the answer.
