porosity (pōros´itē),

n the pres-ence of pores or voids within a structure.
porosity, back-pressure,
n porosity produced in castings resulting from the inability of gases in the mold to escape through the investment.
porosity, occluded gas,
n porosity produced by improper use of the blowpipe (i.e., heating the metal in the oxidizing portion of the flame).
porosity, shrink-spot,
n an area of porosity in cast metal that is caused by shrinkage of a portion of the metal as it solidifies from the molten state without flow of additional molten metal from surrounding areas.
porosity, solidification,
n porosity that may be produced by improper spruing or improper heating of the metal or the investment.

This makes sense if it is assumed that at the higher porosities, some of the pores were open to the surface, so that some water could have infiltrated the pore space, causing a smaller volume to be measured.
However, the large error bars on the disks' composite porosities determined from the individual cylinder measurements is an indication of the local differences in disk porosity that were inherent in the cylinders cut out of those disks.
Using the weights of the dry sediment and the water, effective porosities were calculated for each sediment size.
Further work attempting to relate measured parameters to permeability has revealed that dependence on porosity appears to be weak for samples with porosities less than 18-20[degrees]10 (Sigurdsson 1998b).
Above average porosities are also indicated from these same intervals.
However, approximately 2,100 feet of reservoir quality sands with porosities as high as 28 percent were encountered above basement.
