Challenge Problems
Push your limits with challenges.
Question 1
A closed tank with a diameter of 3 m has a pipe outlet of diameter 0.2 m. If the water level is 5 m high, calculate the discharge through the pipe using the coefficient of discharge of 0.8.
💡 Hint: Calculate the area for the smaller pipe first and then apply the correct formula.
Question 2
In a water supply system, the efficiency of a pump is seen to decline from 85% to 75% as flow rates increase. How does this affect the overall system pressure?
💡 Hint: Think about how energy loss correlates to system performance - higher losses mean lower pressure delivery.
