Question
In between two fluids at two different temperatures (as
shown in the figure) there is a rectangular wall with 30 m?
cros-sectional area and width 20 cm in which energy is
generated by an electrical wiring system. The temperature
distribution in the Wall is given by:
Cold

Hot fluid
at
Wall
160 °C
20 °C
T(x)= 140-620x+52x?
Where T (°C) and x (m)
k= 12 W/m.K
a) Calculate the heat transfer coefficients at the hot and
cold fluid sides.
b) Calculate the energy generation per volume in the
wall
