The coefficients of static and kinetic friction are unitless numbers that are used to calculate static and kinetic friction forces. For any two materials, the coefficient of static friction is always bigger than the coefficient of kinetic friction because it takes more force to start an object movi...

In order to find how much heat energy has been transferred during a non-flow process, we use the non-flow energy equation (NFEE) (see page 17,‘The non-flow energy equation’. Q=W+(U2−U1) In words, this means that the heat energy transferred through the cylinder walls is the wor...

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...
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’...
There are friction forces in addition, only in case the volume element attains a velocity which differs from that of the surrounding fluid. The contribution to the stress matrix due to friction forces is therefore a function of spatial derivatives of the flow velocity, not of the velocity ...
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 ...
