An air duct heater with an electric heating element in an industrial plant is used. 12 m/s velocity perpendicular to the elements from above to the atmospheric air heater and enters at 27 oC. In the duct heater, each row consists of 3 pipes in the flow direction. It consists of 4 rows. In this air duct heater any two pipes The distance between the centers is 22 mm. Each element in the heater is 12 mm outside diameter, 220 mm length and a uniform surface temperature of 330 oC. Air duct Find the heat transfer rate in the heater and the temperature of the air leaving the heater.
