Challenge Problems
Push your limits with challenges.
Question 1
A pipe narrows from a diameter of 20 cm to 10 cm. If water flows at 5 m/s in the 20 cm section, what is the velocity in the 10 cm section? Use Bernoulli's equation for analysis.
💡 Hint: Remember that the flow rate must remain constant.
Question 2
A fluid with density 800 kg/m³ flows through a duct with varying pressure. Use the Reynolds transport theorem to analyze the change in mass flow rate and describe its significance.
💡 Hint: Focus on the relationships established in the Reynolds transport theorem.
