Challenge Problems
Push your limits with challenges.
Question 1
Calculate the forces acting on a control volume with inflows of 100 kg/s and 50 kg/s, with an outflow of 120 kg/s. Assume gravity acts downwards with an appropriate force.
💡 Hint: Remember to account for both inflow and outflow when using momentum equations.
Question 2
Given a turbulent two-dimensional flow causing pressure variations around a structure, determine how momentum coefficients would vary with flow velocity changes.
💡 Hint: Use flow visualization tools to predict how pressure distribution might change with turbulent flows.
