Consider flow of a very low pr number fluid (say pr = 0.005) on a heated flat plate. the plate temperature is kept constant at ts. the freestream velocity is uinf and freestream temperature is tinf. starting with the 2d steady state energy equation, simplify it for this low pr flow with clear justification for the simplifications. perform an order of magnitude analysis on the energy equation to develop an expression for local nu for this type of flow.

What are some properties of transverse waves?

What is the increase in density of a medium due to wave travel?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
