describes how a compound behaves when it transitions from a liquid to a gas," said Tara Lovestead, a NIST chemical engineer and the lead author of the study.
Nevertheless, it is important to note that increasing LSWT leads to higher vapor pressure
Secondly, the low boil point of methanol leads to high possibility of vapor lock by raising the vapor pressure
of methanol-gasoline [12-17].
Representative bioblendstocks identified as meeting the screening criteria described above were blended into a gasoline blendstock or a gasoline surrogate and tested for vapor pressure
(Reid Vapor Pressure
[RVP] as DVPE [dry vapor pressure
equivalent] by ASTM Method D5191), distillation curve (ASTM Method D86), oxidation stability (ASTM Method D525), as well as measurement of RON (D2699) and MON (D2700).

of alcohol- gasoline blends", Energy and Fuels, 24:3647-3654, 2010.
The graphite in reaction zone (2), confined with silica melt at high temperature, has relatively high SiO vapor pressure
; thus its conversion rate for coating formation would be rather fast when compared to the that of reaction zone (1).
The vapor pressure
of methanol, ethanol and 2-butanol is significantly lower than the vapor pressure
of the reference fuel.
However, the vapor pressure
of R-404A exceeds those of R-407A and R-407F on average by 7 psi (48.3 kPa) at -20[degrees]F (-28.9[degrees]C) and nearly 12 psi (82.7 kPa) at 20[degrees]F (-6.7[degrees]C).
The collected low-volatile oil fraction used in vapor pressure
measurement experiments constitutes about 60% by weight of the total oil of pyrolysis.
An absorbent article comprising a malodor control composition disposed therein, said malodor control composition comprising: at least one volatile aldehyde; an acid catalyst having a vapor pressure
of about 0.01 to about 13 at 25[degrees]C.; and wherein said acid catalyst is 5-methyl thiophene carboxylic acid.
"Subcritical water" is water above 140[degrees]C and less than 374[degrees]Cata pressure of 0.36 MPa (i.e., saturated water vapor pressure
at 140[degrees]C) or more.
Here E[T.sub.0] (mm [day.sup.-1]) is the reference ET; [R.sub.n] (MJ [m.sup.-2] [day.sup.-1]) is the net radiation at the crop surface; G (MJ [m.sup.-2] [day.sup.-1]) is soil heat flux density; [T.sub.a] ([degrees]C) is the mean daily air temperature at a height of 2 m; [e.sub.s] [u.sub.2] (m [s.sup.-1]) is the wind speed at a height of 2 m; [e.sub.s] (kPa) is saturation vapor pressure
; [e.sub.a] (kPa) is actual vapor pressure
; [e.sub.s] - [e.sub.a] (kPa) is vapor pressure
deficit (VPD); [DELTA] (kPa [degrees][C.sup.-1]) is the slope of vapor pressure
curve at the daily mean air temperature; and [gamma] (kPa [degrees][C.sup.-1]) is the psychrometric constant calculated as 0.665 x [10.sup.-3] P; in which P (kPa) is the atmospheric pressure.
