4 cards from this section. Quick, good the night before a test.
What is linear momentum?
Think about the definition of momentum in physics.
Define a control volume.
Consider how we isolate a system to analyze forces.
What is the principle of linear momentum conservation?
Think about how momentum behaves in an isolated system.
True or False: Surface forces can include gravitational effects.
Consider the nature of the forces.
Consider a cylindrical tank with inflow and outflow pipes. If the fluid enters the tank at a rate of 5 m³/s and exits at 4 m³/s, calculate the net momentum change in the control volume if the fluid density is 1000 kg/m³.
Focus on the flow rates and how they relate to momentum.
Given a 3D flow simulation around a rectangular structure, determine the forces acting on the structure if the pressure distribution is non-uniform. Describe how you would set up your computational model.
Consider how pressure changes affect forces overall.
