The Geometric standard deviation is 1,37.
The geometric standard deviation can be considered as an error factor.
The geometric mean K is 1.87, and the geometric standard deviation κ is 1.46.
As a result, average size (R e ) and geometric standard deviation are reported.
The observed geometric mean of benzene concentrations was 158 ng m−3, with large geometric standard deviation: 4.9.
The effects of process temperature, T, and precursor volume fraction, φ, on the average diameter, dp, and geometric standard deviation of the particle size distribution are highlighted.
Particulate matter collected was found to be closely approximately at log-normal distribution, with a count median diameter of 1.5 μm and a geometric standard deviation of 1.8.
The reported elemental detection level of our instrument was for aerosols of a number median diameter of 300 nm and the geometric standard deviation of 1200 nm.
Other granule properties, namely the geometric standard deviation, the Hausner index, the angle of repose and the moisture content, were evaluated at the optimal operation conditions.
The geometric mean K becomes 0.93, indicating that observed and computed heights are almost the same, and the geometric standard deviation κ is 1.50.
