heat processes
... EGM is a design concept based upon minimization of irreversible processes. It is a new philosophy: reversible processes are good, irreversible wrong. As a measure of irreversibility the rate of entropy generation in a system is considered. Entropy increase is caused by heat transfer from high to low ...

... Note that, heat transfer is always from the higher-temperature medium to the lowertemperature one. In this case, it is from the oil to the plate. The heat transfer rate is per m width of the plate. The heat transfer for the entire plate can be obtained by multiplying the value obtained by the actual ...

Expansion and Compression of a Gas Isobaric, Isochoric, Isothermal
... The piston being locked in place implies that the process will be isochoric and will be described by a vertical line on the pV diagram. Furthermore, the piston is being held above a hot flame meaning that energy is being transferred into the system in the form of heat. It can be seen from eqn. (6) t ...
