let us consider 50 gram of FCD is taken as Inoculum for laboratory experiment of BMP and FM ratio is 0.2.

As per sample analysis, in 100 grams of FCD contains 67 gram of VS.

So, for 50 grams of FCD, the VS will be ( □(67/100) ×50 ) 33.33 grams.

VS of Food (i.e.CW)=VS of Inoculum× FM Ratio=33.33 ×0.2=6.67 grams

Again as per sample analysis 79 gram of VS contain in 100 grams of CW.

So, 6.67 gram of VS will contain in (□(100/79) ×6.7) 8.50 gram of CW.

Now is it correct way of estimating the amount of CW and FCD based on FM ratio ?
