Rheology By, Tey Yi Shen

Rheology is the study of deformation(dimension change) and flow behavior of matters. It is affected by 3 factor: Stress, Strain, and Time.

For example, water jet cutting, a machining method that uses a jet of pressurized water containing abrasive powder for cutting steel and other dense materials. This method can be used to cut __[|titanium]__, steel, rubber, marble, [|fruits], [|steak], and [|other] with the high speed water. (Time factor can affect the rheology of water)

Other example which related to rheology(i know, rheology is every where..) are mayannase, ice-crea, tomato sauce, jam, tooth paste, sagging paint, lipstick?, lotion, shampoo with beads...







Concentration of matter is not parallel to viscosity. Matter would not deformed without forced. -Solid-elastic Liquid-viscious Solid liquid-viscoelastic

Viscosity is a measure of the resistance of a fluid which is being deformed by either [|shear stress] or [|tensile stress] __**. **__ Unit: Pa.s 1cP=1m Pa.s  eg. 1mPa.s Viscosity water exhibit at 20'C  Temperature must be reported because viscosity of a matter may differ at different temperature.

nit finished yet, to be continue:-) happy learning, happy discovering.
