At the start of process 1 the engine contains 0.035 liters of air at 950 K and 5.7 MPa. We will work this problem process by process.
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.
