2.1.1. Given Data and Assumptions

Try these first

1. 1.

   What is the friction factor typically used for smooth pipes?

   Hint

   Think of pipes with low roughness.

2. 2.

   What does head loss primarily represent?

   Hint

   Consider the energy concept.

3. 3.

   What is the function of the Darcy-Weisbach Equation?

   • To calculate pressure loss
   • To calculate energy loss
   • To determine flow rate

   Hint

   Consider the types of losses that occur in a fluid flow.

4. 4.

   True or False: The friction factor increases for rough pipes.

   • True
   • False

   Hint

   Consider how surface texture impacts flow.

5. 5.

   Calculate the total energy needed to pump water through a 2000 m pipe with given head losses and friction factors to overcome all resistances.

   Hint

   Start by determining total head losses and then apply the power formula.

6. 6.

   Design a pumping system considering varying friction factors for different pipe materials and calculate how much power would be adjusted accordingly.

   Hint

   Use the table values as a base for comparison.
