What is head loss?
Think of it as how much energy is lost while moving through a pipe.
Define the term 'turbulent flow'.
Is this flow smooth or chaotic?
What is the primary cause of head loss in pipes?
Think about how fluid moves inside a pipe.
True or False: A rough pipe surface decreases turbulence.
Consider how bumps impact fluid movement.
A water supply pipe of 200m length has a diameter of 0.1m. Calculate the head loss if the friction factor is 0.03 and the velocity is 3 m/s. Assume g = 9.81m/s².
Don't forget to substitute the values correctly.
Explain how increasing the roughness of a pipe could drastically change the friction factor and impact design decisions.
What happens to flow resistance with increased roughness?
