Challenge Problems
Push your limits with challenges.
Question 1
Given a cylindrical tank with a consistent inflow and outflow rate, calculate the time it takes for the tank to fill up. Assume the input and output rates are equal.
💡 Hint: Focus on the conservation principle; if inputs equal outputs, the volume remains unchanged.
Question 2
Analyze a scenario where a ship moves through a river. How does the relative velocity between the ship and water affect the mass flow rate?
💡 Hint: Estimate the fluid velocity concerning the ship's movement.
