Engine oil (C, =2100 J/kg · °C) is to be heated from 20°C to 60°C at a rate of 0.3 kg/s in a 2-cm-diameter thin walled copper tube by condensing steam outside at a temperature of 130°C (hg =2174 kJ/kg). For an overall heat transfer coefficient of 650 W/m: · °C, determine the rate of heat transfer and the length of the tube required to achieve it. s Te ce = UD sTm こ
