Calculation formula for the rate of wine production:

$$ Rw= \frac {Yq \times G}{Wr} \times 100 $$

In the formula:

Rw - the rate of alcohol production, 10%;

Yq - the annual qualified quantity of wine, 1000KL;

G——the density of wine at 20 ° C, 0.899 t / KL;

Wr - the total annual consumption of grape raw materials, 9000t.
