A food processing plant uses a parallel flow heat exchanger to cool brine solution entening at 70°C at rate of 0.18 kg/s and specific heat is 5 kJ/kg K. Water enters at 20°C with mean flow rate 0.2 kg/s (Cp = 4.18 kJ/kg K). If there is no contrained on length of heat exchanger. Find the exit temperature (°C) of brine solution for maximum heat transfer (correct upto 2 decimal places)
Enter numerical value using the virtual keypad. Round off where necessary.
