Question
Figure shows a heat exchanger designed to cool 5250 kg/h of an ethyl alcohol solution (Cp = 3810
J/kg- °C) from 66 °C to 39 °C. Water (Cp = 4200 J/kg. °C) at 10 °C is pumped at 4750 kg/h to cool

the solution. The tube side fluid flows in a circular pipe with an outside diameter of 25 mm. The
overall heat transfer coefficient is (5.10x10^2) W/(m2.°C ). Find the tube length 'L' for one pass of a
two-pass parallel flow double-pipe heat exchanger as shown in Figure.
Answer should be in m with three significant figures.
Note: Your answer is assumed to be reduced to the highest power possible.
