Webargument that in order to exactly track spatial changes in , the Fick’s first law equation must also be generalized to the form 3 =− ( ) =− − (4) which thus also gives a different equation for the Fick’s second law 𝜕𝑡 = 2( ) 2. (5) When mass flows have components in all directions, Eqs. (4) and (5) should be expressed in the WebFor optical diffusion, Fick's 1st law is expressed as the energy flux J [W cm -2] proportional to the diffusion constant D [cm] and the negative fluence gradient dF/dx: which was obtained by substituting cD for and substituting F/c for C. The factors c and 1/c cancel to yield the above equation.

WebFick's Law describes the relationship between the rate of diffusion and the three factors that affect diffusion. It states that 'the rate of diffusion is proportional to both the surface area … Webthe budget equation becomes x q t c x c D t x c This equation is the 1D diffusion equation. It is occasionally called Fick’s second law. In many problems, we may consider the diffusivity coefficient D as a constant. In that case, the … WebUsing the Fick Principle ’s equation of ( cardiac output = oxygen consumption/arterio-venous oxygen difference), cardiac output can be calculated.
