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.

If the BOD3 of a wastewater sample is 75 mg/l and reaction rate constant k (base e) is 0.345 per day, the amount of BOD remaining in the given sample after 10 days is
The BODs of a domestic wastewater sample is considered to be about 200 mg/l and the DO in it is measured as 0 mg/L. The laboratory staff are preparing to set up a BOD test to determine the actual BOD of the sample. The DO of the dilution water was measured to be 9 mg/I. Which of the following volume ratios of (total volume of BOD bottle = 300 mL) / (volume of wastewater sample) would be most appropriate to use in setting up the BOD bottle for incubation? Select one among the following: (a) 20/1; (b) 50/1; (c) 100/1; (d) 500/1. Justify your selection
You are designing a 20 mgd wastewater treatment plant. To characterize the plant's influent solids, the lab used 90 ml samples of the ty[ical wastewater and the following equipment: Lab Equipment Evaporation Dish Gooch crucible 2.0-micron paper filter 2.0-micron Whatman GF/C filter Lab Measurement Dish + Residue after evaporation Weight 54.2830g 54.2170g 1.5240g 1.6948g 54.349g
A wastewater sample subjected to standard BOD5 test yields a test result of 200 mg/L. The rate constant is 0.18/day at 20°C (to the base 'e'). Another sample of the same wastewater is tested at a temperature of 30°C. The time in days after which the BOD yielded is 200 mg/L is (up to 2 decimal places).
A groundwater borehole at USM engineering campus contains 3000 mg/L of TDS. The flow is 0.32 m³/s. The design TDS concentration of the product water is below 400 mg/L. The net pressure is 40 atm. The membrane manufacturer provides that the membrane has a water flux rate coefficient of 2.2 x 10-6 s/m and a solute mass transfer rate of 1.5 x 10-6 m/s. Calculate the membrane area required for the RO system.
A- An industrial wastewater stream flows at a rate of 13500 m³/d containing 100 mg/L. Suspended solids, ferric sulfate [Fe(SO4)] is used as a coagulant' at a dose of 50 mg/L. a) Assuming that there is very little in water, what is the daily lime dose? b) If the sedimentation tank removes 90% of the inlet solids, what is the daily solids production from the sedimentation tank?
Enter T next to the following true statements and F next to the false statements. Settling of suspended solids in secondary clarifiers is typical of Type II sedimentation. Thickening prior to digestion is common in many wastewater treatment plants because it reduces the size needed for the digester. Based on a temperature of 30°C, a design mean cell residenee time of about 20 days would be reasonable for a completely-mixed anaerobic digester without recycle. A volatile suspended solid is defined as an organic solid that can be oxidized to CO2 (g) at 250°C. The theoretical yield coefficient can be estimated from the observed yield coefficient if the specific 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…

Treating chloride as a conservative substance, and assuming complete mixing of the two streams, find the downstream chloride concentration.

In a BOD test, the amount of organic matter remaining in the wastewater was measured at certain time intervals, instead of measuring the dissolved oxygen content. The amount of organic matterremaining after 4 and 9 d was measured as 52.86 mg/L and 8.11mg/L, respectively. Calculate the ultimate BOD and BOD rate constant k for the wastewater.
