The component of an electronic system dissipating 90 w are located in a 1-m-long circular horizontal duct of 15 cm diameter. the components in the duct are cooled by forced air, which enters at 32ºc at a rate of 0.65 m³/min. assume 85 percent of the heat generated inside is transferred to air flowing through the duct and the remaining 15 percent is lost through the outer surfaces of the duct. you are asked to determine (a) the exit temperature and (b) the highest surface temperature. the following statements explain the procedure
