======Table for relative burning rate======
{{ en:media::burnratiochart.png?30%&link}}
The table shows the relative combustion of all propellant powders in the database. 

There is no standard for sorting such a table. In the published tables of different powder manufacturers or dealers, it is often very different, depending on the preference of the manufacturer. The most frequently used sorting method is **progressivity**.

The table therefore allows different sorting according to different factors, which you can select above the table with buttons.

**Important Note**

The table for the relative burning rate serves only as a rough overview between the different manufacturers. The table makes no statement about how vivacious a powder actually is in the pressure characteristic!

A powder listed in the table at the same level does not therefore mean that it is a 1:1 substitute for a specific powder! It only means that it is probably suitable for a similar application.

====Sorts====
===Progressivity===
Sorts the table by the progressivity factor **//Bp//** of a propellant powder. The progressivity factor and its equation is GRT specific and calculated:
<code>
Bp = sqrt( (2 * (k - 1)) * pow(Ba * phi(z1) * Qex,2) ) / 10000;
</code>
===Brisance===
Sorts the table by the (initial) explosive factor **//Br//** of a propellant powder. The explosive factor and its equation is GRT-specific and calculated:
<code>
Br = sqrt( (2 * (k - 1)) * pow(Ba * Qex,2) ) / 10000;
</code>
===Brisance & Progressivity (combined) ===
Sorts the table using the combined Brisance & Progressivity factor **//Brp//** of a propellant powder. The combined factor and its equation is GRT specific and is the //second absolute moment //((the quadratic mean)) of both single factors:
<code>
Bp = sqrt( ( pow(Br,2) + pow(Bp,2) ) / 2 );
</code>
By combining both factors, a more practicable approximation of the behavior of different propellant powders should be achieved.
