Use Equation (20.26) to determine the inside heat transfer coefficient for a fluid flowing inside a 12 ft (3.6576 m) long, ¾-in tube (16 BWG) at a velocity of 2 ft/s (0.6096 m/s) that is being cooled and has an average temperature of 212°F (100°C) and an average wall temperature of 104°F (40°C).

Consider the following three fluids:

Liquid water n-cetane Air at 2 atm pressure—use a velocity of 20 ft/s (6.609 m/s)

Compare the results using Equation (20.27).
