carbon dioxide (CO2) gas flows at a speed of 2 m/s in a rectangular cross-section channel with a cross-section size of 20 X 10 cm. The inner surface temperature of the channel is 0 °C (constant) and the length is 10 m. The average stack temperature of carbon dioxide along the channel is 27 °C. A) determine the heat transfer occurring by Transport in the Channel; b) determine the inlet and outlet temperatures of CO2 in the channel. 20 cm 10 m 10 cm co,
