Carbon dioxide is compressed in a cylinder in an equilibrium process from initial conditions of p1 = 0.01 MPa, V1 = 0.0040 m3 to a final pressure of p2 = 500 kPa. During the process pV1.22 = constant. Compute the work.
2. Carbon dioxide is compressed in a cylinder in an equilibrium process
from initial conditions of p1 = 0.01 MPa, V1 = 0.0040 m3 to a final pressure
of p2 = 500 kPa. During the process pV1.22 = constant.
Compute the work.
3. A gas held in a cylinder behind a piston undergoes a cycle composed of three
processes:
Process 1-2: an expansion without heat transfer and work is done on the piston
at constant pressure 3kPa where the volume increases from 2m3 to 9m3.
Process 2-3: a compression where 259kJ of heat is added. For this process v2 =
9 m3, P2= 3kPa, v3 = 2m3 and P3 = 13.5kPa.
Process 3-1: a cooling of the gas while the piston is stationary to bring the gas to
its initial state.
Determine the net heat transfer and the heat transfer of process 3-1
