What is the difference between static and kinetic friction? Static friction is the friction force that acts on objects that are not moving. It is the force that keeps things from moving. Kinetic friction is the friction force that acts on objects that are already moving. It acts to oppose ...
The methods are tested on actual data, and topography and friction are included. The results suggest that filtered models are powerful tools for suppressing gravity-inertia waves in the primitive equation models in cases where the horizontal normal modes are difficult to find. Inconsistencies between ...
Bernoulli’s equation is, in fact, just a convenient statement of conservation of energy for an incompressible fluid in the absence of friction. Making Connections: Conservation of Energy Conservation of energy applied to fluid flow produces Bernoulli’s equation. The net work done by the fluid’...
As an example, we will later use the mapping to find an active analog of the tunnel effect. Analogy to dark matter In this section, we use the active-quantum mapping derived above to establish a relation between inertial active matter and dark matter. This illustrates the usefulness of this...
This equation can be used with the position equation for simple harmonic motion (to find the position of the mass at any time), and then substituted into the place of the ∆x in Hooke's law to determine the size of the restoring force at any time t. The complete relat...
Friction factor Cf has been defined (at Eqn 2.3) in terms of pressure gradient dp/dx, allowing Eqn 2.10 to be rewritten: Cf=2rhμ/ρu¯K+2Crh/√K With Re defined as at Eqn 2.1 (not the sole option) this becomes: 2.11Cf=8/Re+2C√K/rhrh2/K Equation 2.11 is unmistakably the ...
Friction Coefficient - λ The friction coefficient depends on the flow - if it is laminar, transitional or turbulent and the roughness of the tube or duct. To determine the friction coefficient we first have to determine if the flow is laminar, transitional or turbulent - then use the proper...

active model I+ contains an analog of the Schrödinger equation in Madelung form as a limiting case, allowing one to find analoga of the quantum-mechanical tunnel effect and of fuzzy dark matter in active fluids. We investigate the active tunnel effect analytically and via numerical continuation...
