Oil is flowing through a 50 mm-ID and 55 mm-OD pure iron pipe at 1 m/s. It is being heated by steam outside the pipe and steam film coefficient may be taken as 11 kW/m2°C. At a particular point along the pipe, the oil is at 50°C, its density is 880 kg/m³, its viscosity is 2.1 cP, its thermal conductivity is 0.135 W/m°C and its specific heat is 2.17 J/g°C. What is the overall heat transfer coefficient at this point, based on the inside area of the pipe? If the steam temperature is 130°C, what is the heat flux at this point, based on the outside area of the pipe?

Oil is flowing through a 50 mm-ID and 55 mm-OD pure iron pipe at 1 m/s. It is being heated by steam outside the pipe and steam film coefficient may be taken as 11 kW/m2°C. At a particular point along the pipe, the oil is at 50°C, its density is 880 kg/m³, its viscosity is 2.1 cP, its thermal conductivity is 0.135 W/m°C and its specific heat is 2.17 J/g°C. What is the overall heat transfer coefficient at this point, based on the inside area of the pipe? If the steam temperature is 130°C, what is the heat flux at this point, based on the outside area of the pipe?
