A double-pipe heat exchanger is used to cool a hot fluid (cp = 3800 J/kgK) entering the heat exchanger at 200°C with a flow rate of 0.4 kg/s. In the cold side, cooling fluid (cp = 4200 J/kgK) enters the heat exchanger at 10°C with a mass flow rate of 0.5 kg/s.
The double-pipe heat exchanger has a thin-walled inner tube, with convection heat transfer coefficients inside and outside of the inner tube estimated to be 1400 W/m^2K and 1100 W/m^2K, respectively. The heat exchanger has a heat transfer surface area of 2.5 m^2 , and the estimated fouling factor caused by the accumulation of deposit on the surfaces is 0.0002 m^2*K/W.
(a) Determine the effectiveness values for the parallel- and counter-flow configurations.
(b) Determine outlet temperatures of the hot fluid for the parallel- and counter-flow configurations.
(c) Determine outlet temperatures of the cold fluid for the parallel- and counter-flow configurations.
