Question:

Air leaves a heat exchanger at about 300°C and 1.5 atm, and the temperature is measured using a thermocouple inside a 1/2-in.-diameter thermowell mounted normal to the airflow. If the gas velocity is 25 ft/s and the pipe wall temperature is 270°C, what error in temperature measurement does radiation cause? (Ignore conduction along the axis of the thermowell.)
