During the Pleistocene, an andesitic volcano named Mount
Mazama grew to a probable elevation of 3000 meters in south-
central Oregon. Near the end of the Pleistocene, three diverse
magma types appeared in the eruptive products associated with Mount
Mazama: l)High-alumina basaltic andesite magma associated with an
early plateau and...
A multiple stage crosscurrent packed column suitable for gas-liquid
mass transfer was constructed and operated. The absorption
column consisted of a rectangular box constructed of plexiglass and
metal. Deflection baffles were positioned at regular intervals on
opposite sides of a central packed section to divert the gas phase
into the...
By an Arnold cell technique, the diffusion coefficients of propanol
and methanol in mixtures of air and argon system have been determined.
The carbon tetrachloride-air system was also studied to verify
the reproducibility of the experimental method.
The diffusion coefficients were compared with experimental
values when available and with values...
A mathematical model was developed to predict the absorption
rate of a slightly soluble gas entrained by a plunging liquid jet. The
single parameter of the model, the transfer factor, TF, was defined
as the summation of the product of the mass transfer coefficient and
interfacial area over all the...
Absorption of methyl iodide by aqueous hydrazine solutions
within spray chambers was studied theoretically and experimentally.
The objective of this work was to evaluate the absorption
rate of airborne methyl iodide by sprays of hydrazine solutions
under conditions expected to exist in post-accident nuclear
reactor containment atmospheres.
Experimental effort included...
A method of measuring interstitial fluid mixing rates for
evaluation of exchange between pore water of estuarine benthic sediments
and the overlying water in a bay is presented. Pore water
movement is monitored by reducing conductivity of the interstitial
fluid within a zone of the benthic sediment to a depth...
Mass transfer from single rising gas bubbles is generally studied
by taking motion pictures of the rising bubbles and analyzing the film
for the instantaneous mass transfer coefficient. In this study, a
different approach was taken for the analysis of mass transfer. This
analysis solved the simultaneous differential equations describing...
