Problem 21.3: Brayton cycle
Please wait for the animation to completely load.
There is a time delay-since the system must be in equilibrium-beforethe 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. To run this Brayton cycle, go through the steps in order. Restart.
- Describe the types of expansions and compressions that are a part of this engine cycle.
- For this monatomic gas, find the work done in each step.
- What is the net work done?
- What is the efficiency of this cycle?
(Note that the high temperature and low temperature reservoirs do not stay at constant temperatures).
