The process of size reduction is followed by size separation of the powdered material. During size reduction, it is not possible to obtain uniform-sized particles. Hence, to separate particles of specified size ‘Size Separation‘ technique is used.
Here Size Separation MCQs are given for self-evaluation purposes. The Size Separation MCQs are based upon the Concept of size separation, Pharmacopoeial standards, methods of size separation, etc.
Size reduction reduces large solid unit masses – vegetables or chemical substances into small unit masses, coarse particles, or fine particles. Size reduction is usually employed in pharmaceutical industries. The size reduction process is additionally mentioned as Comminution and Grinding.
Attempt following Size Reduction MCQ’s
Size reduction reduces large solid unit masses into small unit masses, coarse particles, or fine particles. The size reduction process is also termed comminution or diminution or pulverization.
Attempt Size Reduction MCQ is given below
Size reduction is a process of reducing large solid unit masses into small unit masses, coarse particles or fine particles. Size reduction process is also termed as comminution or diminution or pulverization. Normally, size reduction may be achieved by two methods, namely precipitation or mechanical process. In the precipitation method, the substance is dissolved in an appropriate solvent. This method is suitable for the production of raw materials and bulk drugs. Inorganic chemicals, such as calcium carbon ate, magnesium carbonate, and yellow mercuric oxide, are prepared by precipitation method. In the mechanical process, the substance is subjected to mechanical forces using grinding equipment (ball mill, roller mill, colloid mill, etc.).
Flow of Fluids is a part of fluid mechanics and deals with fluid dynamics. Fluids are a subset of the phases of matter and include liquids or gases. Fluid flow may be defined as the flow of substances that do not permanently resist distortion. The subject of fluid flow can be divided into fluid statics and fluid dynamics.
Drying is a mass transfer process consisting of the removal of water or another solvent by evaporation from a solid, semi-solid or liquid.
