First, determine the filter area, in square feet: Filter area, m … WebChlorides. A sample of mud filtrate (neutralized, if alkaline) is titrated with standard silver nitrate solution, using potassium chromate as indicator. The results are reported as parts per million chloride ion, although actually measured in terms of mg Cl ion per 1000 cm 3 of filtrate. To determine the chloride content of an oil mud, the ...

The antisymmetric part corresponds to rotation of the uid element and is called the vorticity tensor. To see this, let’s consider a ow that is rotating, but not deforming, and also a ow that is deforming, but not rotating. In two dimensions a rotating ow is u /( y;x) and a deforming ow is u /(x;y).
