Isothermal or adiabatic process

  1. Jan 5, 2007 #1
    :confused: :confused: i was reading my lecture note over the half term but i am still a bit confused and i was wondering if someone could describe in detail, using a p-v diagram, a well known engineering cycle which specifies a isothermal or adiabatic process.

    Thanks you very much

    Have you tried to understand what happens in an ideal 4-stroke IC engine?

    Consider a simple refrigeration process. What are the four basic steps in the process and how can you model them?

    Note: One of the four steps can be isenthalpic as well as adiabatic. Which one is it?
