Solve one problem only and submit: Problem 5-1 (Energy balance) A Piston Cylinder device contains 5 kg of air (assume ideal gas). Initial temperature is 22â Electrical energy is supplied to the system at a rate of 2 kJ/s. The content of the system is stirred by a paddle wheel to ensure uniform temperature everywhere in the system (See Figure). The paddle wheel passes energy to the system at a rate of 0.2 kJ/s. The process is stopped after 10 minutes and the final temperature is 67 °C. The whole process takes place under constant pressure of 200 kPa. 1- Determine the initial and final volume of the system. 2- Determine the heat transferred from the cylinder. 3- Is the process adiabatic? Justify 4- Show the process on a T-v and a P-v diagrams. P AIR ant
