It is an ideal case, as per the levenspiel popcorn example when there is a uniform distribution of material in reactor then the mean residence time remain constant because.

1) there is a constant rate of input as well as output.

2) a fixed amount of accumulation. i.e. no dead zone, bypassing, channelling etc.

On the other hand, space time is the time required to treat a reactor volume completely,
So space time == mean residence time.
