A high pressure steam turbine receives steam from a boiler under unknown conditions. The isentropic efficiency of the turbine is 75% and it produces 1MW. The high pressure turbine outlet steam is at 1.4 MPa under saturated conditions. The high pressure turbine exhaust supplies 1000kg/min for use in a process, in addition to an unknown flow of steam that follows the path, being supplied to a low pressure turbine that produces 820kW when it releases steam at 10kPa and has a isentropic efficiency of 60%. The steam that was used for the process (out of the high pressure turbine) after being used, returns to the cycle taken by the pump, which also takes the outlet of the condenser and does so at 10kPa as saturated liquid.
