👉 In physics, a viscous fluid is a substance that exhibits a tendency to resist change in its state due to its viscosity. It can be described as having mass density or pressure distribution that changes with velocity and has an associated resistance to flow. This resistance is typically expressed in terms of the Reynolds number (Re) and may vary depending on the properties of the fluid, such as viscosity, temperature, and composition.

viscoidal

👉 In physics and engineering, a "viscoid" is a type of material that exhibits viscosity or rigidity. These materials are used in various applications such as flow mechanics, heat transfer, and fluid dynamics. In particular, they are used in the design of pipes, turbines, and pumps to control their velocity and pressure.

viscoid

👉 Viscoid is a term that refers to an emotion characterized by vividness and intensity rather than coloration. It originated in the 18th century but is now widely used today as slang. Imagine, for instance, someone feeling so strongly about something that they could vibrate with excitement or intensity like a vibrissa (a type of mosquito). This term has its uses, especially when it comes to describing feelings that are both intense and fleeting.

Example sentence: "He was deeply in love with her, and his heart felt as though it were vissicoid."
