Convection Heat transfer internal flow

Consider water flowing in a heated tube. The tube is 14 m longwith an inner diameter of 1 cm. The heat
is added at 1500 W/m2 uniformly along the tube. Water flows at 0.3m/s. Use the following water property
? = 1000 kg/m3, ? = 1.4 × 10?3 kg/m·s, cp =4.2 kJ/kg·K, k = 0.58 W/m·K, and determine

1. Heat transfer coefficient at the tube exit.
2. Tube surface temperature at the exit, with the mean inlettemperature of water at 7°C.
