Pipe Flow Experiment: Head Loss and Friction Factor in Pipe Flow

Why do we need a pump to pump fluid from place to place?

What does a pump do anyway?

How much is energy loss in a piping system?

What size/power of the pump is needed?

What’s the fuss about pipe flow and loss in pipe anyway?

Can you recommend a pump for this Alaskan oil pipeline?

What is energy or head loss anyway?

How do we quantify it?

How do we measure it?

How much is “energy loss” in pipe flow?

If I increase the volume flowrate twice, how much is the energy loss

increased?

What is the required power input at the pump (heart, etc.)?

Is Mr. Moody fairly correct?
