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) The Reynolds number is approximately:
b) According to the Reynolds number obtained, it can be stated
that the flow is in regime:
- lamellar
-turbulent
-transition
c) Determine the friction factor f assuming smooth
pipe:
