Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Calculate head loss for a flow of 4 L/s with K = 0.05.

💡 Hint: Remember H_L = K Q^2.

Question 2

Easy

What is the primary goal of the Hardy Cross Method?

💡 Hint: Think about the flow in a closed loop.

Question 1

What does the Hardy Cross Method primarily analyze?

  • Flow in open channels
  • Flow in pipe networks
  • Unsteady flow

💡 Hint: Consider where you have seen this method applied.

Question 2

In the Hardy Cross Method, a positive ΔQ indicates what?

  • True
  • False

💡 Hint: Think about what achieving zero head loss means for the flow.

Challenge Problems

Push your limits with challenges.

Question 1

Given a looped pipe network with pipes A, B, C, and D having respective K values of 0.03, 0.05, 0.02, and 0.04, if the flows are distributed as 20 L/s, 15 L/s, and 10 L/s, calculate ΔQ for the network. Assume all other conditions are ideal.

💡 Hint: Remember to calculate head losses from each pipe, sum them, and look for inequalities to adjust the flows.

Question 2

You have a network with an inflow of 50 L/s and a desired output of 40 L/s. Using the Hardy Cross Method, detail the iterative steps you'd take to reach the desired output, including ΔQ adjustments.

💡 Hint: Focus on ensuring the head loss equation balances out while adjusting Q values.
