Design a heat exchanger for a process where hot air (80°C) needs to be cooled down to 30°C using water (10°C) as the cooling medium. The flow rate of hot air is 2 kg/s and the desired outlet temperature of the cooled air is 35°C. The maximum allowable pressure drop for air side is 50 kPa and for water side is 100 kPa. Design the heat exchanger using the LMTD (logarithmic mean temperature difference) method and calculate the required area of heat transfer.
