Challenge Problems
Push your limits with challenges.
Question 1
Calculate the energy loss for a fluid flowing through a pipe of length 100m with a friction factor of 0.02 and a flow rate of 0.05 m³/s.
💡 Hint: Make sure to find the corresponding diameter first using the flow rate.
Question 2
In a three-reservoir system, if one tank has an elevation of 5m and the others are 2m, calculate the required pressure at the higher tank to maintain flow.
💡 Hint: Don't forget to notate each height and how they influence potential energy.
