Challenge Problems
Push your limits with advanced challenges
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.
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!
