The Mechanical Engineering exam syllabus. The Question and answers have been prepared Can you explain this answer? for Mechanical Engineering 2023 is part of Mechanical Engineering preparation. Pseudo- plastic substances are non- Newtonian fluids for whicha)Dynamic viscosity decreases with the time for which shearing force applied.b)Dynamic viscosity increases with time for which shearing force applied.c)Dynamic viscosity decreases as the rate of shear increasesd)Dynamic viscosity increases as the rate of shear increases.Correct answer is option 'C'. Governed by the orientation and alignment of their constituent particles or molecules Commonly observed in thixotropic fluids such as paint, ink, and ketchup Exhibit a decrease in dynamic viscosity as the rate of shear increases In summary, the characteristics of pseudo-plastic substances can be summarized as follows: When a shearing force is applied, the particles or molecules start to align themselves in the direction of the force, which reduces their resistance to flow. The behavior of pseudo-plastic substances can be explained by the fact that the flow of these fluids is governed by the orientation and alignment of their constituent particles or molecules. ![]() This behavior is commonly observed in thixotropic fluids such as paint, ink, and ketchup. This means that the resistance to flow decreases as the shearing force increases. “fluid” in Diccionari català-valencià-balear, Antoni Maria Alcover and Francesc de Borja Moll, 1962.Pseudo-plastic substances are non-Newtonian fluids that exhibit a decrease in dynamic viscosity as the rate of shear increases.“fluid” in Diccionari normatiu valencià, Acadèmia Valenciana de la Llengua.“ fluid”, in Gran Diccionari de la Llengua Catalana, Grup Enciclopèdia Catalana, 2023.“fluid” in Diccionari de la llengua catalana, segona edició, Institut d’Estudis Catalans.( figuratively ) fluid, fluent, smooth estil fluid ― fluid style.( Balearic, Central, Valencian ) IPA ( key): /ˈflujt/įluid ( feminine fluida, masculine plural fluids, feminine plural fluides).“ fluid”, in The Century Dictionary, New York, N.Y.: The Century Co., 1911, →OCLC.“ fluid”, in Webster’s Revised Unabridged Dictionary, Springfield, Mass.: G.Cadell, in the Strand, 1791, →OCLC, page 245. ^ “ Fluid” in John Walker, A Critical Pronouncing Dictionary, London: Sold by G.Korean: 유체 (ko) ( yuche ), 유동체 ( yudongche )īokmål: væske (no) m or f, fluid (no) n Nynorsk: væske f, fluid n.German: Fluid (de) n, Flüssigkeit (de) f.Finnish: fluidi (fi), juokseva aine, virtaava aine.Czech: kapalina (cs) f, tekutina (cs) f.Not related to English flow, which is a native, inherited word from *plew.
