By circulating water inside a copper tube with an internal diameter of 5 cm, it is desired to heat 100 kg/min of water to 60 °C. The water has a temperature of 20 °C. The surface of the tube is kept at 100 °C by condensing steam on the outside. Determine the required length of tube. The properties of water at 40 °C are: ρ = 994.59 kg/m³, Cp = 4.1784 X 103 J/kg K, v=0.658 X 10-6 m2/s, k = 0.622 W/mK and Pr=4.34.
