Water at 15°C is heated by passing through a copper pipe with an
inner diameter of 2 cm. The heat is obtained from the process of
condensation of water vapor on the outer surface of the pipe which
occurs at 120°C. The water is required to leave at 65°C with a mass
flow rate of 0.2 kg/s.
a) Determine the length of pipe (in m) needed based on the
calculated heat transfer area.
b) With the help of the Darcy-Weisbach equation and the
calculation of the friction factor, determine the pressure drop (in
Pa) for the length of pipe calculated in the previous point.
