Repeat Problem 19.21 for laminar flow.

Problem 19.21

For fully developed turbulent flow, assuming all variables not mentioned are held constant:

What is the effect of doubling the flowrate on the pressure drop?

What is the effect of increasing the pipe diameter by 25% on pressure drop?

What is the effect of increasing the pipe diameter on flowrate?

What is the effect of increasing pipe length on pressure drop?

What is the effect of increasing pipe length on flowrate?

What is the effect on pressure drop of replacing one long pipe segment with two equal-sized pipe segments of half the length placed in parallel?
