WebbThe residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, … Webb6 maj 2024 · Standard Deviation is a measure of how much the data is dispersed from its mean. A high standard deviation implies that the data values are more spread out from the mean. Standard Deviation is often denoted by the symbol SD or the Greek symbol σ or the Latin letter ‘s’. SD or σ is used for population standard deviation and ‘s’ is used ...
