... A piston-cylinder device contains 12 kg of saturated R-134a vapor at 3.2 bar. An electric source supplies 8 A current to a resistor within the cylinder for 4 minutes and there is heat transfer of 400 kJ to the system. During these energy interactions, the pressure is maintained constant in the cylin ...

Lumped element model
The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
