You just purchased a 400-L rigid tank for a client who works in the gas industry. The tank is delivered pre-filled with 3 kg of air at a temperature of 25C.

Problem 4: Air flows into an open system and carries energy at the rate of 100 kW. When the air leaves the system, the energy rate it carries is 250 KW. In the meantime, the system receives 350 kW power and negligible heat flux.
