In this project, the objective was to calculate the optimal air pressure produced by a compressor that could maximize the work per unit mass obtained from a turbine which is connected to it. The pressurized air from the compressor would pass through a heat exchanger, a geothermal source, and then it would enter the turbine. In order to find the best possible pressure from the compressor, differential calculus along with thermodynamic functions which describe the behavior of both the turbine and compressor were used. The result was that the pressure had to be 1.41 bars and the resulting net work per unit mass obtained from the turbine would be 3.20 kilo joules per one kilogram of air.
