Minimum Flow Area Heat Exchanger, Top View Shown by Heavy Line Air 0.3 m Consider the cross-flow heat exchanger for heating air with hot gasses as shown opposite. Conditions are 0.4 kg/s for air mass flow rate, 0.65 kg/s for gasses mass flow rate, 40 °C for air inlet temperature and 870 °C for inlet gasses temperature. Both fluids are approximately at atmospheric pressure. 40 tubes 27.5 cm Section A-A 25 cm 2.26 cm O 1. Determine the overall heat transfer coefficient based on the tube Tube detail outside surface. 2. Determine the effectiveness of this heat exchanger 3. Determine the exit temperature of the hot and cold fluid and the mean temperature difference. 4. Determine the pressure drop in the shell pass and tubes. ttttttt Hot Gas in Air in 5 cm- 2.5 cm- 22.5 cm 4 cn 5 cm
