Challenge Problems
Push your limits with challenges.
Question 1
A pipe with a diameter of 10 cm has water flowing through it at 2 m/s, and the outlet pressure is 150 kPa. Calculate the hydraulic gradient and the expected energy gradient line, considering frictional losses.
💡 Hint: Use A = π*(d/2)^2 to find cross-sectional area and calculate expected energy.
Question 2
Design a system incorporating a pump and a turbine. The pump needs to lift water from a lower reservoir by 5 m against atmospheric pressure. Give the required input power considering efficiency ratings of both devices.
💡 Hint: Use the power output formula, and apply efficiency ratings from standard sources.
