A BOD test is to be run on a sample of wastewater that has a 5 day BOD of 210 mg/L. The intial dissolved oxygen, DO of a mix of distilled water and wastewater is 7.9 mg/L.  Roughly what is the maximum volume of wastewater should you put in the bottle if you want to have at least 2.0 mg/L of DO remaining at the end of 5 days?

Fluid Materials

In general terms, anything that flows can be termed as a fluid. In other words, a fluid is any substance that cannot resist shear forces and deforms continuously under the application of external shear forces. Fluid materials differ completely from solid materials such as metals and alloys. For instance, if we consider two infinitesimally small cross-sectional areas of fluid materials and solid materials, and apply shear forces to these elements, both the elements will undergo deformation. Upon releasing the shear force, the element of the solid materials will regain its original orientation, but the element of the fluid materials will keep on deforming continuously under the action of the shear force.
