Challenge Problems
Push your limits with challenges.
Question 1
A tank has water flowing in at a rate of 5 L/min while water flows out at a rate of 3 L/min. Determine the change in the tank's mass flow considering it starts at 100 L. What happens over time?
💡 Hint: Set up a mass balance using inflow and outflow rates.
Question 2
In a moving control volume like a submarine, the pressure changes due to the movement forward through water. Explain how conservation of mass is maintained in this scenario.
💡 Hint: Consider how the submarine's speed affects the water pressure and flow rates.
