📌Knudsen Number: 📕
The Knudsen number (Kn) is a dimensionless number defined as the ratio of the molecular mean free path length to a representative physical length scale.
K<<1=> Dense fluid flowing through a pipe in the continuum regime. Particle-particle interactions are important, and the mass flow rate Q is proportional to R^4
K>>1=> Flow of a gas in a long pipe with diffusive scattering at the walls. Q is proportional to R^3
🔺KNUDSEN FLOW:👉👉The transitional range between viscous flow and molecular flow is known as Knudsen flow. Knudsen flow is a type of gas flow that occurs in very small channels, typically on the order of micrometers or nanometers in size. It is characterized by a high degree of molecular collisions and is often described as a "ballistic" flow.
