Challenge Problems
Push your limits with challenges.
Question 1
Consider a pipe flow scenario with a diameter of 1.0 m, with a roughness ε = 0.5 mm. If the velocity of fluid flowing through it is 3.0 m/s, calculate the Reynolds number and determine whether the flow is laminar or turbulent.
💡 Hint: Utilize the Reynolds number formula.
Question 2
A pipe's friction factor is determined as 0.02 after using the Moody Chart. If the length of the pipe is 200 m and the fluid has a velocity of 4 m/s, calculate the head loss over the length of the pipe.
💡 Hint: Plug the values into the head loss formula to compute.
