The vertical rear window of an automobile is of thick- ness l = 8 mm and height h = 0.5 m and contains fine- meshed heating wires that can induce nearly uniform volumetric heating, /m3). (a) consider steady-state conditions for which the inte- rior surface of the window is exposed to quiescent air at 10°c, while the exterior surface is exposed to air at −10°c moving in parallel flow over the sur- face with a velocity of 20 m/s. determine the vol- umetric heating rate needed to maintain the interior window surface at ts, i = 15°c.
