مقاومت سیال در برابر تغییر شکل برشی

AI overview

Viscosity is a fluid's internal resistance to flow—essentially how "sticky" or thick a fluid is, caused by friction between moving layers of the fluid. This property matters because it affects how all fluids behave when they move, from how easily oil pours to how air flows around objects.
