A device that recovers heat from high-temperature combustion products involves passing the combustion gas between parallel plates, each of which is maintained at 350 K by water flow on the opposite surface. The plate separation is 40 mm, and the gas flow is fully developed. The gas may beassumed to have the properties of atmospheric air, and its mean temperature and velocity are 1000 K and 60 m/s, respectively. What is the heat flux at the plate surface
