Challenge Problems
Push your limits with challenges.
Question 1
A fluid flows through a pipe with a sudden contraction from diameter 0.2m to 0.1m. Using Bernoulli's equation, calculate the expected pressure drop due to energy losses if the flow velocity before the contraction is 3m/s.
💡 Hint: Use continuity equation to find velocity after contraction.
Question 2
A globe valve experiences a pressure drop of 15 kPa while managing a flow of 0.5 m³/s. If the K factor for this valve is 0.18, calculate the approximate energy loss attributed to the valve.
💡 Hint: Recall the head loss relationship: h = K(v²/2g).
