Question
Consider water is flowing through a
pipe with a 10 cm diameter at a flow
rate of 0.2 kg/s. The inlet mean
temperature of the water is 25 °C. If
the wall of the pipe is heated with an
electric resister generating heat at a
rate of 5 kW and maintaining a
uniform wall heat flux, determine the
average convective heat transfer
coefficient between water and wall of
the pipe.
The properties of water at this
temperature are given as; specific
heat capacity Cp = 4.18 kJ/kg-K,
thermal conductivity k = 0.607 W/m-
K, Density p = 997 kg/m³, and
kinematic viscosity v = 8.9 x 10-
7 m²/s.
