    The estimates you obtain from the analysis represent the best achievable performance that may be obtained from a heat engine. The volume occupied by the working fluid, when the piston reaches the top dead centre, is known as clearance volume. We shall only consider the effect of irreversibilities upon compression and expansion processes. T C is practically limited by the temperature of the sea or ocean which is nearby the power plant ie o C or K. It is the ratio of work done to the displacement volume. The cycle consists of four processes: a quasi-static adiabatic compression in the inlet and compressor, b constant pressure heat addition in the combustor, c quasi-static adiabatic expansion in the turbine and exhaust nozzle, and finally d constant pressure cooling to get the working fluid back to the initial condition.
