Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the mass flow rate of water entering a control volume where the diameter of the inlet pipe is 0.1m, velocity is 2m/s, and density is 1000kg/m³.

💡 Hint: Remember to calculate the area of the pipe first.

Challenge 2 Hard

A ship with a moving control volume travels at 5m/s, while water velocity relative to the shore is 3m/s. Calculate the relative velocity of water across the ship's hull.

💡 Hint: Think about the reference point for the velocities.
