5. In a nuclear plant, electrical power is generated due to nuclear fission reaction in a reactor. A nuclear reactor consists of vertical plates of 2.2 m high and 1.4 m wide has been intended to undergo free convection. The maximum temperature of the plate is restricted to 960 °C while the lowest temperature of bismuth (control rods) is 340 °C. Calculate the maximum possible heat dissipation from both sides of each plate. Accustom the following formula, to determine the heat transfer coefficient and heat transfer rate: Nu 0.13 (Gr.Pr) 0.333 (Thermo-physical properties of bismuth at 650°C are p = 10 kg/m³, μ= 3.12 kg/m-h, Cp = 150.7 J/kg °C, k = 13.02 W/m °C)
