Challenge Problems
Push your limits with advanced challenges
A 6-inch diameter pipe transitions into a 12-inch diameter pipe suddenly. Calculate the head loss when the water velocity in the smaller pipe is 3 m/s. Assume g = 9.81 m/s².
💡 Hint: Ensure proper calculations for area ratios and remember units.
You have a pipe system where the K entrance is 0.4, and the flow exits into a tank. If the velocity is 1.5 m/s, calculate the head loss at the entrance.
💡 Hint: Stay focused on the correct formula for entrance loss.
