![Water at 50°C flows through an automobile radiator tube 0.5 cm inner diameter, 50 cm long
with a mean velocity of 1 m/s. The surface of the radiator tube is at 30°C. Determine the heat
transfer coefficient using Colburn Analogy.
[Use friction factor f= 0.316 Re5 for turbulent and f= 0.184 Re for laminar.]
