The core of a high‐temperature, gas‐cooled nuclear reactor has coolant tubes of 20‐mm diameter and 780‐mm length. Helium enters at 600 K and exits at 1000 K when the flow rate is 8 × 10^−3 kg/s per tube.
(a) Determine the uniform tube wall surface temperature for these conditions.
(b) If the coolant gas is air, determine the required flow rate if the heat removal rate and tube wall surface temperature remain the same. What is the outlet temperature of the air?
