Water (4.1 L/min) is flowing in a tube "D = 3 cm, L= 5 m" and is to be heated from 15°C to 59.8°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) If turbulent flow use Dituss- Boetler relation Nu= 0.023 Re0.8 .Prn Properties : p = 992.1 kg/m3 , Cp 4179 J/kg. °C, k 0.631 W/m°C, Pr = 4.32, v = 0.658E-6 m2/s
