Saturated liquid water flows through 2 cm ID stainless steel tubes at 200 g/s. The water is at 80oC and the inside surface of the tubes is 200oC. (a) Determine the convection heat transfer to the water per unit length of tube and (b) predict the convective heat transfer after ten years when the inside of the tubes is coated with a film so that the ID is now 1.9 cm. If scaling of the tube was creating the reduction of the tube diameter, that came accompanied with an increase in the tube wall roughness of 0.2mm, discuss if the increased tube roughness compared with the smooth tube wall will affect the heat transfer coefficient and how.
