Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the definition of head loss in a pipe?

💡 Hint: Think about what happens to energy as fluid moves through a pipe.

Question 2

Easy

What is considered a major loss in a pipe?

💡 Hint: Focus on the primary cause of losses in fluid mechanics.

Question 1

In flow through pipes in series, the discharge is:

  • a. Variable
  • b. Constant
  • c. Increasing

💡 Hint: Think about how water behaves when pushed through connected tubes.

Question 2

In a straight pipe, if the diameter increases, the friction loss generally:

  • a. Increases
  • b. Decreases
  • c. Remains unchanged

💡 Hint: Visualize how wider pipes handle flow compared to narrower ones.

Challenge Problems

Push your limits with challenges.

Question 1

A plumbing system consists of three pipes in series with lengths of 30 m, 50 m, and 20 m, and diameters of 0.1 m, 0.15 m, and 0.2 m respectively. The friction factor for all is 0.015. Calculate the total head loss if the velocity of fluid in the system is 2 m/s.

💡 Hint: You need to apply the formula individually and account for each section.

Question 2

Two pipes with different diameters, 0.2 m and 0.1 m, are connected in series. The flow rate is required to be 3 m/s in the larger pipe. What effect will this have on the velocity in the smaller pipe, and how would that affect head loss?

💡 Hint: Remember that smaller diameters generally lead to increased speed and, thus, increased friction.
