Thermodynamics in piston-cylinder arrangement — Lesson 2

This lesson covers the solution to a complex thermodynamics problem involving a piston-cylinder arrangement. The problem involves a 1 kg mass of water initially enclosed within a volume of 1 cubic meter in a vertical piston-cylinder arrangement. The lesson explains the process of heat addition from a source at 400°C until the temperature rises to 400°C. The lesson also covers the calculation of the final state of water, work done, heat transfer, and second efficiency. The instructor uses specific volume, entropy, and other thermodynamic properties to solve the problem, providing a practical understanding of thermodynamics.
