Chapter 8, Problem 8.20(choose chapter or problem)
Water at 300 K and a flow rate of 5 kg/s enters a black,thin-walled tube, which passes through a large furnacewhose walls and air are at a temperature of 700 K. Thediameter and length of the tube are 0.25 m and 8 m,respectively. Convection coefficients associated withwater flow through the tube and airflow over the tubeare 300 W/m2?K and 50 W/m2?K, respectively.(a) Write an expression for the linearized radiationcoefficient corresponding to radiation exchangebetween the outer surface of the pipe and thefurnace walls. Explain how to calculate this coef-ficient if the surface temperature of the tube isrepresented by the arithmetic mean of its inletand outlet values.(b) Determine the outlet temperature of the water, Tm,o.
