All solids smaller than 90 percentile formation sand are probably interstitial fines.

All solids smaller than 90 percentile formation sand are probably interstitial fines. Correct Answer True

The statement is true. All solids smaller than 90 percentile formation sand are probably interstitial fines. In the petroleum industry, we mean controlling of load-bearing solids when we talk about sand control.

The outcome of the spot speed studies carried out at a certain stretch of a highway are as follows. 50th percentile speed = 46 km/h ; 75th percentile speed = 54 km/h ; 85th percentile speed = 60 km/h ; 95th percentile speed = 75 km/h ; 98th percentile speed = 84 km/h ; 100th percentile speed = 95 km/h What is the speed (in km/h units) to be taken to check the geometric design elements.
Consider the following statements regarding crystal defects: 1. In metals, a self-interstitial introduces relatively large distortions in the surrounding lattice because the atom is substantially larger than the interstitial position in which it is situated. 2. All crystalline solids do not contain vacancies and, it is possible to create such a material that is free of these defects. 3. Impurity point defects are found in solid solutions, of which there are two types: Substitutional and interstitial.  Which of the above statements is/are correct?

The following are certain operating problems of a rapid sand filter: 1. Sand depth should never be depleted by more than 10 cm. 2. Air binding results due to development of negative head and formation of air bubbles in the filter sand. 3. Water softening with lime-soda leads to incrustation of sand. 4. Bumping of filter bed is caused due to negative head. Which of the above statements are correct?
Consider the following statements regarding removal of impurities from water: 1. Settleable solids are removed by filtration. 2. Volatile solids are removed through sedimentation. 3.

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
