2 cards from this section. Quick, good the night before a test.
What is the equation for head loss in a pipe using Darcy-Weisbach?
Think about the factors influencing energy loss.
What does the friction factor depend on?
Recall the acronym R-F-V-L.
What is the purpose of the Darcy-Weisbach equation?
Think about what you lose energy to in a pipe.
True or False: Minor losses in a fluid system can often be ignored in calculations.
Recall how fittings and bends add up in head loss.
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.
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?
Don’t forget to factor in efficiency and any head losses!
