2. In class, we discussed several different flow scenarios for which we can make enough assumptions to simplify the Navier-Stokes equations enough to solve them and obtain an exact solution.

1. Consult the form of the x-direction Navier-Stokes equation below that we discussed in class. (For this problem, only the x direction equation is shown for simplicity). Note that the equation provided is for a Cartesian coordinate system. In the spaces below, indicate which of the following assumptions would allow you to eliminate a term from the equation. If one of the assumptions provided would not allow you to eliminate a particular term, write "none" in the space provided. du ди at ( + + + 매일) du ди = - Pgx dy др dx ²u Fu u + fl + ax2 ay² az2 - дх - Əz 1 2 3 4 5 6 7 8 9 Assumption Flow is in the horizontal direction (e.g. patient lying on hospital bed) Flow is unidirectional in the x-direction Steady flow We consider the flow to be between two flat, infinitely wide plates There is no pressure gradient Flow is axisymmetric Term(s) in equation

why did the expert subtract the force exerted by the hand and the elbow by the force due to the weight of the hand and forearm and force exerted by the tricep. Does the order matter and how do you determine what to put first. Question 4 AP, CHAPTER 13 FROM BASIC BIOMECHANICS 8TH EDITION

The drawing illustrates the dispersion of light by a prism. The prism is made from a certain type of glass, and has a cross section shaped like an equilateral triangle. The indices of refraction for the red and violet light in this type of glass are 1.649 and 1.694, respectively. The angle of incidence for both the red and violet light is 60.0°. Find the angles of refraction at which the (a) red and (b) violet rays emerge into the air from the prism. Glass prism Incident light Normal (a) Normal Incident light Red (660 nm) (b) Violet (410 nm)

A glass block (n = 1.56) is immersed in a liquid. A ray of light within the glass hits a glass- liquid surface at a 70.0° angle of incidence. Some of the light enters the liquid. What is the smallest possible refractive index for the liquid?

The drawing shows a crystalline slab (refractive index 1.995) with a rectangular cross section. A ray of light strikes the slab at an incident angle of 01 = 35.0°, enters the slab, and travels to point P. This slab is surrounded by a fluid with a refractive index n. What is the maximum value of n such that total internal reflection occurs at point P? Ме Bu
