05401 IUPAC Gold Book - rise velocity 10.1351/goldbook.R05401 R05401 current synonym: vertical rise velocity 1 The vertical component of the velocity of the volatilized component in the observation space (in \(\rm{mm s}^{-1}\)). It depends on the flame temperature, the solute nebulized, the observation height and the gas flow rate. PAC, 1986, 58, 1737.
