stream? Q2/ An ideal gas initially at 600 K and 10 bar undergoes a four step mechanically reversible cycle in a closed system. In step 1-2, pressure decreases isothermally to 3 bar; in step 2-3, pressure decreases at constant volume to 2 bar; in step 3-4, volume decreases at constant pressure; and in step 4-1, the gas returns adiabatically to its initial state. Assum C₂=(7/2) R and C₂ = (5/2) R. Calculate Q, W, AU, and 4H for each step of the cycle?
2 kg of Refrigerant-134a contained in a piston-cylinder device undergoes a reversed Carnot cycle. Some important information about the cycle is: ● At the beginning of the adiabatic compression (State 1), the refrigerant is a saturated vapor. ● The adiabatic compression ends when the temperature of the refrigerant is 30 degrees C● The refrigerant is 50% vapor by mass at the end of the isothermal heat rejection process. ● The adiabatic expansion process ends when the pressure of the refrigerant is 132.82kPaConsulting example 7-6 in your text might be helpful in understanding some aspects of this problem. a) Represent this cycle on a T-S diagram. On your diagram, clearly indicate the values of the specific entropy and temperature at every state. b) Explain (briefly) why the process curves take the shapes you indicated on your T-S diagram in part a.
