Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A cylindrical tank is filled with water that is drained through a smaller exit pipe. If the area of the tank's opening is 10 cm² and the exit pipe's area is 2 cm², how does this relate to the continuity equation? Calculate the velocities given the inlet velocity is 1 m/s.

💡 Hint: Focus on the relationship between area and velocity from the equation.

Challenge 2 Hard

If a fluid with a density of 1000 kg/m³ flows through a control volume with a velocity of 3 m/s, what would be the mass flow rate if the cross-sectional area is 5 m²?

💡 Hint: Apply the definition of mass flow rate from density, area, and velocity.
