Arrays of parallel equally spaced vertical thin plates are connected to the surface of a natural convection air heater. The plates are maintained at a fixed temperature of 75°C by embedding electrical heaters. The plates are 305-mm high and 305-mm long. The whole set-up is in an area where the air temperature is 20°C. The total width of the array cannot exceed 150-mm. What is the plate spacing in millimeters that maximizes heat transfer from the array?
