Q 2. Air at 400°C and 1.7 bar flows through a horizontal 8.2-cm ID pipe at a velocity of 50.0 m/s. I. Calculate Ék (W)? Assuming ideal gas behavior and Mol.Wt (Air)=29 g/mol. I. If the air is cooled to 250°C at constant pressure, what is AER? III. Why would it be incorrect to say that the rate of transfer of heat to the gas must equal the rate of change of kinetic energy?
