Challenge Problems
Push your limits with challenges.
Question 1
Calculate the power output of a turbine where the pressure drop from point 1 to point 2 is 4000 N/m², flow rate is 0.1 m³/s, and efficiency is 85%.
💡 Hint: Remember the formula for power, working through the units carefully.
Question 2
Analyze a situation where fluid flows through a pipe with a sudden enlargement (200 mm to 400 mm) and a rise in pressure head of 0.01 m. How does this affect flow rate?
💡 Hint: Keep in mind the relationship of velocity to diameter in the continuity equation.
