Question
Water (Cp = 4200 J/kg. °C) is used
cool an unknown fluid (with a given
Cp = 3810 J/kg.ºC) using a two-pass
parallel flow double-pipe heat
exchanger. The unknown fluid enters
the heat exchanger at 66 °C with a
flowrate of 1.46 kg/s. Water can be
supplied at 10 °C and 1.32 kg/s. If the
heat exchanger cool the unknown
fluid to 39 °C, then the maximum heat
transfer between the fluids is equal to
150 kW
230 kW
310 kW
475 kW
