Water, at 1 bar pressure and a mean temperature of 40°C, flows in a horizontal pipe that is 5 cm in diameter. The mean velocity is such that
The flow is thermally developed. The pipe is subject to UHF boundary conditions, such that
The pipe is made of stainless steel and is 3.5 mm thick.

Calculate the wall surface temperature Ts, using the correlation of Morcos and Bergles (1975). Examine whether the application of this correlation is justified.
