Definition
Viscidity is essentially another word for viscosity, describing the degree to which a fluid resists flow. It's all about the internal friction within the liquid. 🍯 A substance with high viscidity is thick and slow-moving, like honey or syrup. Low viscidity means it flows easily, like water. It’s a fundamental property that influences how fluids behave in various applications. It can also be thought of as a measure of a fluid's 'thickness'.
