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 Nusselt number using the Gnieliski
equation:
b) The convective heat transfer coefficient (h) in IS units
(W/m2*C)
is approximately:
