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 Ek (W), assuming ideal gas behavior.
(b) If the air is heated to 400°C at constant pressure, what is ΔEk Ek (400°C) — Ek (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?
