2.3.2. Current Research and Applications

Try these first

1. 1.

   Define friction factor.

   Hint

   Think about the role of friction in flow.

2. 2.

   What is the Darcy-Weisbach equation used for?

   Hint

   Consider the factors involved in fluid movement.

3. 3.

   What is the role of the friction factor in fluid flow?

   • A measure of pipe roughness
   • A measure of energy loss due to friction
   • An indicator of flow speed

   Hint

   Consider how friction impacts movement.

4. 4.

   True or False: Minor losses are always greater than major losses in a pipe.

   • True
   • False

   Hint

   Reflect on the sources of loss.

5. 5.

   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.

   Hint

   Ensure to determine V using the appropriate formula or given values.

6. 6.

   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.

   Hint

   Convert flow to weight properly for calculations.
