## Perfectly Stirred Reactor

A Perfectly Stirred Reactor (PSR) is an ideal reactor in which perfect mixing (homogeneity) is achieved inside the control volume. It is assumed to be operating at a steady state. A mean residence time is defined in PSR as density multiplied by volume divided by mass flow rate. Solving conservation equations, we get the mixture fractions and temperature of products for given inlet conditions of mixture factions and temperature at a given system pressure.
