Fluid Mechanics 51 Conservation of Mass for a Control Volume

############################# Video Source: www.youtube.com/watch?v=Xl9aIdxQHQ0

This segment derives the conservation of mass (or continuity) equation applied to a control volume from the Reynold's Transport Theorem. We also introduce the mass flow rate terminology. • Table of Contents: • 6:49 - Mass Flow Rate • Module 5-- Finite Control Volume Analysis - Conservation of Mass • Conservation of mass is obtained by substituting B=mass and b=1 into the Reynold's Transport Theorem. The time rate of change of the mass of the coincident system = time rate of change of the mass of the contents of the coincident control volume + net rate of flow of mass through the control surface. • Student Learning Outcomes: • After completing this module, you should be able to: • 1) Select an appropriate finite control volume to solve a fluid mechanics problem. • 2) Analyze whether the case is steady vs. unsteady, constant density vs. variable density, incompressible vs. compressible, uniform flow vs. non-uniform flow. • 3) Apply conservation of mass principle to the contents of a finite control volume to get important answers This material is based upon work supported by the National Science Foundation under Grant No. 2019664.
