Along cylindrical rod of diameter 200 mm with thermal conductivity of 0.5 w/m·k experiences uniform volumetric heat generation of 2.4 x 104 w/m3 . the rod is encapsulated by a circular sleeve having an outer diameter of 400 mm and a thermal conductivity of 4 w/m·k. the outer surface of the sleeve is exposed to cross flow of air at 27°c with a convection coefficient of 25 w/m2·k. (a) find the temperature at the interface between the rod and sleeve and on the outer surface. (b) what is the temperature at the center of the rod?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
