Question:

Air at 300°C and 130 kPa flows through a horizontal 7-cm ID pipe at a velocity of 42.0m/s

(a) Calculate E_k (W), assuming ideal gas behavior.

(b) If the air is heated to 400°C at constant pressure, what is ΔE_k E_k (400°C) — E_k (300°C)?

(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?
