A horizontal stainless steel (conductivity, k = 15 W/mK) circular pipe of outside and inside diameters of 0.50 m and 0.45 m, respectively, carries fluid (convection coefficient, h = 200 W/m2K) and passes through a large room whose air and solid surfaces are at 20oC. Given that the outside of the pipe is un-insulated, with asurface temperature of 80oC, and has a convection coefficient of 20 W/m2K and an emissivity of 0.9, what is the total heat transfer rate (Watts) from the pipe per metre length and the temperature of the fluid in the pipe? Stefan Boltzmann constant is 5.67 x 10-8 W/m2K4.
