3241: Aerodynamics and Flight Mechanics Name: _________________ Concept Quiz #4 The purpose of this concept quiz is to examine the application momentum equation for part of a control surface analysis. The momentum equation is: ( 29 = + F dS n U U dV U dt d S V d d d d ˆ ρ ρ What is the y-component of momentum flux across this surface? Assume steady flow, no

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
