3 cards from this section. Quick, good the night before a test.
Define friction factor.
Think about the role of friction in flow.
What is the Darcy-Weisbach equation used for?
Consider the factors involved in fluid movement.
What is the role of the friction factor in fluid flow?
Consider how friction impacts movement.
True or False: Minor losses are always greater than major losses in a pipe.
Reflect on the sources of loss.
A water system comprises a 3000 m long pipe with a diameter of 0.25 m. If the friction factor is 0.03 and several valves introduce additional losses amounting to 8 m, calculate the total head loss.
Ensure to determine V using the appropriate formula or given values.
How much power is required to pump water 40 m high through a pipe where major losses are 12.5 m and minor losses are 3.5 m? Assume 70% pump efficiency.
Convert flow to weight properly for calculations.
