Lecture
This lecture covers fluid kinematics and the control volume approach using the Reynolds Transport Theorem (RTT). It begins with an overview of the Eulerian and Lagrangian approaches to fluid flow, emphasizing the distinction between a control volume and a system. The instructor explains the importance of mass conservation, Newton's second law, and energy conservation in fluid dynamics. The lecture details how to apply the Reynolds Transport Theorem to relate these physical laws to a control volume framework. The instructor illustrates the concepts with examples, including a nozzle flow problem, demonstrating how to derive the continuity equation and solve for flow velocities. The discussion highlights the significance of choosing an appropriate control volume and the implications of steady flow conditions on the governing equations. The lecture concludes with a transition to the next chapter, focusing on practical applications of the control volume approach in engineering problems.
