6.1) A boiler produces 25 kg/s of steam at 3 MPa and 600 °C, cools the condenser with seawater so that the outlet is at 45 °C, then a reheating at 500 kPa up to 400°C is carried out, then a low-pressure expansion is carried out in the turbine. Determine: A) The net power output B) The total heat transfer in the boiler
