Quiz – ungraded (answers will be on bSpace) (1) For creeping flow past a sphere shown below, write down the r and θ components of v = - Uez In spherical coordinates, ____ ≤ θ ≤ ____ and ____ ≤ φ ≤ ____ (2) Given the following differential equation for h : ∂ ∂ + ∂∂ + ∂ ∂ = h t ση xh3 3h x3 U h x 0 where σ , η , and U are constants, we would need ____ boundary conditions in the ____-direction and ____ ________ condition for ________ in order to solve. Assuming R and H to be the characteristic length scales for x and h , respectively, and that the second and third terms in the above differential equation are of the same order of magnitude, show that H must scale as RCa 1/3 , where Ca = ηU / σ is the capillary number. (3) Fill in the blanks or circle the correct items regarding the falling-film geometry shown below. ∂ ∂ p x = _____ , ∂ ∂ p y 0 ∂℘∂ x = ∂∂ - x ρ ____ g x = _______ , g y = _______ Write the simplified form of the x-component of the Navier-Stokes equations for this geometry.

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.
