Major Minor losses

Major loss in a pipe is due to

• pipe fittings

• entry and exit losses

• friction

• none

Head loss due to friction is given by

• None

Minor loss in a pipe is due to

• expansion and contraction

• pipe fittings

• presence of valves

• All of the above

In a pipe of length 300m, water is being carried at a velocity of 1m/s. The diameter of the pipe is 100mm. If the friction factor associated with the flow condition is 0.015, what is the head loss? Assume g = 10m/s²

• 1m

• 2.25m

• 3m

• .225m

The Moody's diagram is a plot between f and ___________

• k/D and Reynolds number

• Reynolds number

• only k/D

• None

The maximum value for friction factor f in a pipe line usually doesn't exceed

• 1.0

• 10.0

• 0.001

• .1

For a turbulent flow, the Re is generally

• greater than 4000

• less than 4000

• equal to 4000

• None

For a laminar flow, the Re is generally

• less than 2500

• greater than 2500

• equal to 2500

• None

What is the friction factor f when the flow has a Re of 1000

• 0.064

• 0.013

• 0.004

• 0.15

The friction factor f for laminar flow is determined using

• f = Re/64

• f = 0.316/Re

• f = 64/Re

• None
