- In this segment, we start discussing the 2nd law of thermodynamics. We illustrate that processes have directions. Before covering the Kelvin-Planck Statement, we discuss thermal reservoirs (essentially heat source and heat sink) and introduce a heat engine. We go over the boiler, pump, turbine, and condenser components of a steam power plant and derive the thermal efficiency. At last, we introduce the Kelvin-Planck Statement of 2nd law, which states it is impossible for any device operating on a cycle to receive heat from a reservoir and produce a net amount of work.
