Italicized values are from ideal gas relations or air tables. Bold values are calculated. The boundary work is then calculated. Finally we use the conservation of energy to determine the heat transfer. We start by determining our mass.
Italicized values are from ideal gas relations.
Bold values are calculated. For the final state we will apply our process description to get the final volumes, then isentropic condition to determine the temperature and then calculate our pressure form the ideal gas law. Then our boundary work will be calculated from PdV. Finally, we use the conservation of energy to determine the heat transfer. To determine the temperature at 3 we find that we can use the v r in the air tables as follows. Italicized values are from ideal gas relations or tables.
