Two large flat porous horizontal plates are separated by a relatively small distance L. The upper plate at y-L is at temperature TL, and the lower one at y-0 is to be maintained at a lower temperature TO. To reduce the amount of heat that must be removed from the lower plate, an ideal gas at TO is blown upward through both plates at a steady rate. Develop an expression for the temperature distribution and the amount of heat q0 that must be removed from the cold plate unit area as a function of the fluid properties and gas flow rate. Use the abbreviation Ø: pCpvyL per K Two large flat porous horizontal plates are separated by a relatively small distance L.
