A fuel element operates at a linear power rating of 65 kW/m. It is cooled by single phase heavy water flowing at a velocity of 9 m/s. Using the Dittus-Boelter convective heat transfer correlation calculate the temperature of the outside wall of the fuel sheath assuming the following parameters: = Sheath outer diameter = 13.12 mm Element length = 490 mm Equivalent hydraulic diameter = 7.55 mm Coolant density = 835 kg/m Coolant specific heat = 4.95 kJ/kg/K Coolant viscosity = 0.000106 kg/m/s Coolant thermal conductivity = 0.505 W/m/K Coolant bulk temperature 280°C =
