OD of a wastewater sample is determined by incubating the BOD bottles at four different temperatures, 5, 15, 20, 35, and 50°C. i The ultimate BOD of the sample incubated at 10°C would be-----compared to the sample at 50°C. ii. The reaction rate constant, k for sample incubated at 35°C would be- compared to the sample incubated at 5°C

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.
