QUESTION 2 Consider the heat engine cycle shown below (or see Figure_engine.pdf) that consists of Processes 1-4 discussed in previous assignments. This cycle of processes is known as a Stirling engine. This engine has applications described in Wikipedia (https://en.wikipedia.org/wiki/Stirling_engine). It differs from the Carnot engine presented in the videos because it has both reversible and irreversible processes. The irreversible processes make it less efficient than a Carnot engine. However, it is easier to make a Stirling engine. р 2 4 3 + V₂ V₂ To V Use the following values for this question. Tc = 293 K Th=373 K Va = 0.2 m³ Vb = 1.0 m³ The system consists of 2 moles of a monatomic gas. Calculate the total work in joules done by the gas during the full cycle of all four processes: 1, 2, 3, and 4. Consider carefully all four processes as well as the sign (+/-) of the work done in each process. Do not include units in your answer and write the numerical value in normal form.
