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.

Enter T next to the following true statements and F next to the false statements. The theoretical yield coefficient can be estimated from the observed yield coefficient if the specified growth rate constant is known. Air flotation would likely be more efficient for thickening waste activated sludge than primary sludge, while the opposite would be true for gravity thickening. The net mass of cells produced in the activated sludge process equals the total cell mass synthesized minus the cell mass wasted as waste activated sludge. Although the main purpose of an equalization basin is to give a relatively constant flow rate to downstream treatment operations and processes, a secondary benefit is the removal of some of the total suspended solids.
A 50 mL sample of water was placed in a 300 mL BOD bottle, dilution water was added to fill the bottle, and the sample was incubated for 5 days. The initial DO concentration was 7.25mg/L, and at the end of the incubation period the concentration was 2.28 mg/L. Determine BOD5 for the sample. Assuming a typical value for the reaction constant, k, of 0.20 d-1, determine the ultimate BOD of the sample
