👉 An intensive fluid is a type of fluid that is characterized by its high viscosity, meaning it flows very slowly and has a thick, syrupy consistency. Unlike dynamic fluids, which move easily and can be easily compressed, intensive fluids resist flow and deformation under pressure. This property makes them particularly important in various scientific and engineering contexts, such as in the study of polymers, lubricants, and biological fluids like blood, where their resistance to flow plays a crucial role in function and behavior.
