Role of partition in work extraction from multi-particle Szilard Engine

In this work we have calculated analytically the work extraction in multi-particle Szilard engine. Unlike the previous studies, here we have introduced the biasing in the measurement procedure by inserting the partition at an arbitrary distance from the boundary. We found the work extraction to be symmetric with respect to a position- which is half way between the boundary walls. The work extraction is also calculated as a function of number of particles and it shows to saturate to a certain value for large number of particles. We find that work extraction can be made larger for multi-particle engine when the partition is inserted in the middle.
