Question
Q7) The components of an electronic system are located in a 1.5-m-long horizontal duct whose cross section is 20 cm x 20 cm. The components in the duct are not allowed to come into direct contact with cooling air, and thus are cooled by air at 30°C flowing (1) SOF wierza -11-22 over the duct with a velocity of 200 m/min. If the surface temperature of the duct is not to exceed 65°C, determine the total power rating of the electronic devices that can be mounted into the duct. Damme Lore
