Otto cycle

    1. The problem statement, all variables and given/known data

    i have an mechanical engineering problem. A gas taken thru a 4-process cycle has 1-2 isothermal volume ratio rv,2-3 isobaric constant pressure,3-4 isentropic reversable adiabatic and 4-1 isochocric constant volume. How do i formulate the thermal efficiency equation for it?

    2. Relevant equations



    3. The attempt at a solution

    I'm assuming heat is added at stages 2-3 and ejected at 4-1 while 2-3 is the expansion processes, if that's the case thermal eff.= Heat supplied/work done in expansion, where the basic thermodynamic relations and steady state gas equations would help you through this

    However, if this is not the case I'm afraid the information you provide is insufficent
