Space time equals the mean residence time
WebThe graph is the distribution of residence times about the mean. The bottom line of output gives us the integral of the PDF, the mean normalized residence time, the concentration of A and B and, finally, the conversion of A. We see from this graph that with the mean residence time of 100 and variance of 2, this appears to be a sharp distribution.

WebResidence time is a broadly useful concept that expresses how fast something moves through a system in equilibrium. It is the average time a substance spends within a specified region of space, such as a reservoir. For example, the residence time of water stored in deep groundwater, as part of the water cycle, is about 10,000 years.
