Heat formula in current
A heat current is a kinetic exchange rate between molecules, relative to the material in which the kinesis occurs. It is defined as , where is heat and is time. For conduction, heat current is defined by Fourier's law as where is the amount of heat transferred per unit time [W] and is an oriented surface area element [m ] WebUsing the variable H to represent heat current, this gives you the equation: H = dQ / dt If you've taken pre-calculus or calculus , you might realize that a rate of change like this is …
