Attempt All sub parts from each question.Newtonian and non-Newtonian fluid: Viscosity is the physical property that characterizes the flow resistance of simple fluids. Newton’s law of viscosity defines the relationship between the shear stress and shear rate of a fluid subjected to a mechanical stress. The ratio of shear stress to shear rate is a constant, for a given temperature and pressure, and is defined as the viscosity or coefficient of viscosity. Newtonian fluids obey Newton’s law of viscosity. The viscosity is independent of the shear rate. Example: air, water, alcohol etc. Non-Newtonian fluids do not follow Newton’s law thus, their viscosity (ratio of shear stress to shear rat e) is not constant and is dependent on the shear rate. Example: honey, ketchup etc. Non-Newtonian fluids can be categorized into four types based on the way a fluid’s viscosity changes in response to variations in shear rate.• Pseudoplastic: Materials whose viscosity decreases as the shear rate increases. This type of flow behavior is sometimes called shear thinning. Example: Cake batter, agar-agar and fruit juice concentrates, nail polish etc.• Dilatant: M aterials whose viscosity increases as the shear rate increases. This type of behavior is sometimes called shear-thickening. Example: Suspension of corn starch in water and candy compounds etc..• Thixotropic: M aterials whose viscosity decreases when sheared at a constant rate over time. Example: Yogurt, gelatin gel, honey etc.• Rheopectic: M aterials whose viscosity increases when sheared at a constant rate over time. Example: Printer ink, gypsum paste etc.Q. Viscosity of pseudoplastic non-Newtonian fluid
