Differentiate between “conservation of mass” and “conservation of volume”. Under what conditions they become identical? In a compressor, whether both or anyone (which) is valid?
From the video, whatever I've learned that is writing - 1. For steady flow, there is no net accumulation of mass with the control volume provided that the control volume it self should not be deforming in the time scale of instants considered. 2. In steady flow at any instant in time, the incoming & outgoing mass fluxes are same so that the mass content at any instant in control volume remains the same.
I sometimes wonder why I even go to class when I have you to break it down. I don't even need the textbook if not for questions that may come out on test to practice ahead of time
At 3:08, it was stated that with steady flow, the term with the time derivative will equal 0 and because of this, the second term will also equal 0. However, on the next slide, we begin analyzing a steady flow device and acquire different results. Can you please clarify how this happened?
The control volume consists of both the entrances and exits, as well as the walls of the device. The area is broken up into the five inlets/outlets, and the remaining area which is the walls.
