Question
Water is flowving in a tube “D = 3 cm, L=5 m" and is to be heated from 15°C to 47°C by
applying a uniform heat flux on the outer surface of the tube by electric resistance
heater. If the Power rating is 11kW and the convective heat transfer
coefficient is 864 W/m².K, what is the surface temperature at the exit
“°C"?
