USEFUL WORK BASED ON THE SECOND LAW OF THERMODYNAMICS FOR FLOW PROCESSES

We know that the steady flow energy equation for any kind of open system,


For an open system, the maximum useful work, (Wu)max is same as Wmax due to the rejection of heat to the atmosphere itself. So,

(Wu)max = Wact = Wmax

Similar to closed system, substituting equation (3.31) in below formula,
