Steam engines are used in the generation of electrical energy, in an electrical power plant you want to know their final energy efficiency. The rigid container of the steam engine contains a hot fluid that is cooled while being stirred by a fan. Initially, the internal energy of the fluid is 800 kJ, but during the cooling process it loses 500 kJ of heat. For its part, the wheel performs 100 kJ of work on the fluid. A) Make the graphical representation of the process, take into account that no mass crosses its borders during the process. B). Determine the final internal energy of the fluid and ignore the energy stored in the fan.
