Challenge Problems
Push your limits with challenges.
Question 1
Consider a tank where water is flowing in and out. If the inlet flow rate is 5 L/min and the outlet flow rate is 3 L/min, determine the change in water volume in the tank after 10 minutes.
💡 Hint: Remember to calculate the net inflow over time.
Question 2
A piston compresses a gas in a cylinder. The initial volume is 10L, and the final volume is 2L. If the initial density is 1.2 kg/m³, calculate the new density assuming mass is conserved.
💡 Hint: Use the mass conservation principle to find the new density.
