The closed Rankine cycle of a CHP station processes 1800 tonnes of working fluid per hour. The boiler raises the temperature of the high-pressure water from 45°C at 25 MPa to the required 550°C isobarically. The superheated fluid enters the turbine. As it passes through the turbine, the steam pressure falls as it gives energy to the turbine blades. The water leaves the turbine as saturated steam at 0.10 MPa. How much shaft work is generated? • Derive, simplify, and solve the energy balance for this system. • Show all your workings in a neat manner: State your assumption(s), show all formulae, calculate step-by-step, use units at every step, and round results correctly.
