Question 1

What is the purpose of the Darcy-Weisbach equation?

  • To calculate pressure loss
  • To determine velocity
  • To calculate head loss due to friction

💡 Hint: Think about what you lose energy to in a pipe.

Question 2

True or False: Minor losses in a fluid system can often be ignored in calculations.

  • True
  • False

💡 Hint: Recall how fittings and bends add up in head loss.

Challenge Problems

Push your limits with challenges.

Question 1

A pipe system has total lengths of 1500 m and 1000 m of two sections with diameters of 0.3 m and 0.15 m respectively. Calculate the total head loss if the first section has a friction factor of 0.03 and the second 0.04, considering a fluid velocity of 3 m/s.

💡 Hint: Break it down by calculating head losses for each section before combining them.

Question 2

Design a pump for a system that needs to lift water over 45 meters through a pipe with a total head loss of 20 meters. How would you calculate the required horsepower considering efficiency?

💡 Hint: Don’t forget to factor in efficiency and any head losses!
