سوال عن الديناميكا الحرارية
Application 5
3moles of gas undergoes a thermodynamic cycle consisting of three process.
Process 1-2: constant specific volume
Process 2-3: constant temperature expansion
Process 1-2: constant pressure compression.
At state 1, the temperature is 300 K and the pressure is 1 bar. At state 2 the pressure is 2 bars.
1. Sketch the cycle on P-v coordinates.
2. Determine the temperature in state 2 in K
3. Determine the specific volume at state 3 in m3/kg
The perfect gas constant is equal 8.314 J/kg. K
