Course Objectives:
This course is a follow up of Graduate Fluid Mechanics I. We will first introduce the differential form of equations of fluid mechanics. Then, we will go in more depth into the concepts of potential flow, viscous fluid flow, boundary layers, flow in open channels, and compressible flow.
