Water (5.2 L/min) is flowing in a tube "D= 3 cm, L=5 m" and is to be heated from 15°C to 59.9°C by applying a uniform heat flux on the outer surface of the tube by electric resistance heater. What is the power rating of the resistance heater (kW)? 0.8 If turbulent flow use Dituss-Boetler relation Nu=0.023 Re Pr 3. Properties : p =992.1 kg/m , C,- 4179 J/kg.°C k= 0.631 W/m°C, Pr= 4.32, v= 0.658E-6 %3D P m /s
