How do you do the math?
This cycle depends on only 2 well known devices with 2 equally well known properties. Below is a graph showing the cycle on Volume Pressure Plot. The Calculations are based on
Heat = Volume-Beta
Work = Heat initial - Heat Final,
where Beta for air is 0.4.
Using the volume pressure graph for air,
choose 1 Liter as unit volume
1 Bar as unit pressure
then Work per unit area = 10 Newtons/cm2 times 10 cm2*Meters or 100 Newton-meters or Joules
and Heat energy per unit area = 100 Joules / Beta (0.4) or 250 Joules of heat per unit area.
From these formulas all work and heat can be calculated. Those calculated values shown on following graph. |
