The steady-state flux and current at every location in the medium are given by Ф ≅( S(2^1/2)/π*d)* e^-a/(2)^1/2*L. Since there are isotropic sources that are equally distributed and emit s neutrons per cm3/s
According to Fick's first law, which stipulates that diffusion flow is proportional to concentration gradient, steady-state flux diffusion processes are identified by this property. Diffusion coefficient or diffusivity are other names for the proportionality constant, D. It is expressed in m2/sec. J x can be used to represent the one-dimensional case for steady-state flux. The movement of electrical charge carriers like electrons is known as current. Positive and negative locations both experience current flow. The ampere is the SI unit for calculating electrical current (A). The movement of electrical charge carriers like electrons is known as current. Positive and negative locations both experience current flow.
Ф ≅( S/4*π*d)* e^(r/l)/r
