Extracted text: A liquid metal Gows at a rate of 5 kg/sec through a 5 cm diameter stainless steel tube. It enters at 425°C and is heated to 450°C as it passes through the tube. If a constant heat flux is maintained along the tube and the tube wall is at a temperature 20°C higher than the liquid metal bulk temperature, calculate the area required to effect the heat transfer. At constant heat flux, Nu = 4.82 +0.0185PE0.827 relation holds good. Properties of the compound: µ = 1.34 x 10-3 kg/m.sec; Cp W/m.K; Pr = 0.013. 0.149 kJ/kg.K; k = 15.6 %3D
