Challenge Problems
Push your limits with advanced challenges
In a complex piping system, each path carries fluid with different diameters. Path one has a diameter of 0.2 m, path two has 0.3 m, and path three has 0.5 m. Calculate the flow velocities if each path's flow rate is 5 m³/h.
💡 Hint: Use the formula for area of a circle and convert the units accordingly.
Given a turbulent flow in a pipe where the Moody Chart indicates a friction factor of 0.02 and a Reynolds number of 10,000, calculate the head loss over a distance of 100m if the diameter is 0.5m.
💡 Hint: Ensure you plug in the correct numbers for all variables.
