    Yes I understood. thanks. I hv another doubt. what is the role of heat in AD & CD ?

    eduncle-logo-app

    We have to find the heat extracted from the source. Now heat extracted from the source will be in AB and BC path. AB path is a constant volume heat addition process and BC is a constant pressure expansion process. CA is a constant volume heat rejection process. AD is a constant pressure contraction process. That is why we only take AB and BC for heat extraction.
