How do you solve a diffusion equation with a negative diffusion coefficient?
Such an equation would represent an ill-posed problem for all positive time (i.e. the solution is not defined). The irreversibility of diffusive processes is closely related to the second law of thermodynamics. Petr
Example of coefficient?
coefficient
What is an example of coefficient?
2X 2 is the coefficient
What is the coefficient of n plus 3?
The coefficient is the number that multiplies a value. For example, the coefficient of 4x is 4. If n+3 is in brackets in the form (n+3) then the coefficient is one. If not the the coefficient of n is also 1.
What is a binomial coefficient?
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
Diffusion coefficient of sodium chloride in water?
diffusion coefficient nacl in water at difrent concentration
How diffusion coefficient depends on temperature?
The diffusion coefficient depends on temperature in direct negative exponent.
What is apparent diffusion coefficient?
The definition of apparent diffusion coefficient is a measure of the extent of diffusion of the water molecules that are in tissue. It is a term used in reference to an MRI.
What is the air diffusion coefficient of thiophene?
on the basis of molecular simulation the self diffusion coefficient of thiophene comes out to be 3.274e-9 m2/s
How do you solve a diffusion equation with a negative diffusion coefficient numerically It is unstable at all. Solving it with finite difference is best?
Diffusion does not require the cell to expend ATP. Therefore, diffusion is considered a type of passive transport.
How does diffusion coefficient depend on the molecular properties of the solute and solvent?
It doesn't. Ever since it was a child it has been a free spirit. It's parents expected it to depend on at least one of the two, but the diffusion coefficient just wanted to dance.
What is the relation between apparent diffusion coefficient and mean diffusivity on DTI?
It is the same. ADC=MD.
What is the diffusion coefficient of Fluorescein in water?
About 300 um^2/s at 20 degree C.
Theory of gas diffusion coefficient of acetone using winkelmann method?
The theory of gas diffusion coefficient of acetone using the winkelmann method is to diffuse the gas into a volatile liquid. This can be done by confining the liquid in a small narrow tube and observing the rate of evaporation.
How do you find the diffusion coefficient?
It is possible to calculate the diffusion coefficient of a liquid. You would set up a liquid-liquid diffusion coefficient sample. Use the variables W for solvent molecular weight, F for?æsolvent association factor, V for solvent viscosity, M for solvent molal volume, and T for system temperature.The equation you use is D(A,B) = [7.4T (FW) ^0.5]/ [V (M^0.6) * (10^8)].?æ
