2 Outline • Derive the Conservation of Linear Momentum – Forces on CV, stress tensor – Examples! – Momentum flux correction factor, β • Learning Objective: Be able to apply linear momentum equation to a problem • Announcements – I will be out of town on Monday. No office hours. I will be in Tuesday if you need to see me.
