Problem 21.1: Three cycle engine

Please wait for the animation to completely load.

There is a time delay-since the system must be in equilibrium-before the initial change of state occurs.

You must go in order.

In this animation N = nR (i.e., kB = 1). This, then, gives the ideal gas law as PV = NT. Restart.

  1. Describe the types of expansions and compressions that are a part of this engine cycle.
  2. For this ideal gas, what is γ (the adiabatic constant, or the ratio of the specific heat at constant pressure to the specific heat at constant volume)?
  3. Find the work done in each step.
  4. What is the net work done?
