Water flows at 1 kg/s in a 10 mm diameter tube and is to be heated from 25 to 75 °C. The tube surface temperature is maintained at 100 °C. Using the following properties for the water: p = 998 kg/m, Cp = 4171 J/kg K, k = 0.651 W/m K, µo = 4.71 x 10“ kg/m s, Pw = 2.82 x 104 kg/m s and Pr = 3.02. a) What is the required tube length for these conditions?
