(10 points) Air at 300C and 130 kPa flows through a horizontal 7-cm ID pipe at a velocity of 42.0 m/s. a. Calculate the rate of kinetic energy transport, k(W), assuming ideal-gas behavior. b. If the air is heated to 400C at constant pressure, what is Ak = k(400C) - k (300C)? c. Why would it be incorrect to say that the rate of transfer of heat to the gas in Part (b) must equal the rate of change of kinetic energy
