Thermal Fourier Number

Analogous Mass Fourier Number

The rate at which heat is transferred or conducted through a substance is directly proportional to the

Fourier's Law:

Conduction will take place if there exist a temperature gradient in a solid (or stationary fluid) medium.

This vCalc equation computes the total harmonic distortion (THD) of an electrical signal from the voltages (`V_n`) of the harmonic components comprising the signal.

Degrees Brix, `{::}^oBx`, defines the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by weight (% w/w).

Degrees Plato, `{::}^oP`, defines the sugar content of an aqueous solution. One degree The Plato scale defines the amount sucrose in volume of solution and represents the strength of the solution as percentage by weight (% w/w). The Plato scale has been used since 1843 and is closely related to the Brix scale.
