In a manufacturing unit making iron rods, the heat generated from the furnaces is used to generate steam. The steam in turn is used to generate electricity for the manufacturing unit. What type of manufacturing system is this?

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
