The temperature of a hot gas stream flowing in a duct (90cm) length and (30cm) diameter is to be measured by using a spherical thermocouple junction (2mm) in diameter placed at the center of the duct. The duct wall is at (30 ° C) and the gas stream is at (110 ° C). If the heat is being transferred to the thermocouple at the rate of (560 W / m²) from the gas, and both the thermocouple and the duct are considered black, what will be the reading of the thermocouple?
