A temperature probe is used to measure the temperature of gas flowing through a pipe. The gas temperature indicated by the probe is 600°C, and the pipe wall temperature is measured as 375°C. The temperature probe is cylindrical with a diameter of 2 mm and an insertion depth of 2.5 cm. The equivalent thermal conductivity of the temperature probe is 100 W/m2.°C; it is assumed to be uniform over the probe surface. Determine the true gas temperature (°C), accounting for conduction along the probe; assunme an adiabatic fin tip.
