Suppose there is a rectangular metal plate in the Oxy-plane with vertices (1, 1), (5, 1), (1, 3) and (5, 3). There is a heat source at the origin that heats the plate. Suppose the temperature at a point in the plate is inversely propotional to the distance of this point to the origin. Suppose there is an ant at the point (3,2). In which direction should the ant creep such that it gets to the cooler place fastest?
Hint: Gradient vector.

Consider the flow of a liquid metal past a flat plate (Pr << 1). We have shown that for a constant wall teemperature, T_o, the Nusselt number is given by Nu = 0.564*(Re^1/2)*(Pr^1/2). Show that if the surface is not a constant temperature, but is instead providing a constant heat flux, that the Nusselt number becomes Nu = 0.886*(Re^1/2)*(Pr^1/2). Start with the following expression for the temperature profile within a semi-infinite body with a constant heat flux boundary condition T...

A thin rectangular plate coincides with the region defined by 0 ≤ x ≤ π, 0 ≤ y ≤ 1. The left end and right end of the plate are insulated. The bottom of the plate is held at temperature zero and the top of the plate is held at temperature f(x) = 4 cos(6x) + cos(7x). Set up an initial-boundary value problem for the steady-state temperature u(x, y).
