Challenge Problems
Push your limits with advanced challenges
A tank experiences varying inflows and outflows. Calculate the change in volume over time, considering the inflow rate is twice the outflow in a steady state.
💡 Hint: Derive the relationship based on given conditions and integrate over the required time period.
Determine the forces acting on a control volume when the fluid enters at high velocity while the control volume itself is moving.
💡 Hint: Consider external influences and forces from within the fluid body.
