Air enters a duct (100 cm *10̟cm*10 cm) at 32°C at a rate of 0.28m /min to cool 138 W electronic component placed on the duct . Assuming 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. What is the exit temperature of air (°C)? C,= 1007 J/kg. C, v =1.654×10-5 m²/s, p 1.146 kg/m³ Pr = 0.7268, k = 0.02625 %3D %3D W/m. °C
