Question

35000kg of whole milk containing 4% fat is to be separated in 6hours period into skimmed milk with 0.45%fat and cream with 45%.calculate flow rate of two output s cream from cream seperater​

Answer 1

Explanation:

Total mass= 36000 / 6 = 6000 kg

Fat = 6000 x 0.04 = 240 kg

6000 - 240 = 5760 kg water.

Let the mass of cream be x kg then its total fat content is 0.45x. The mass of skim milk is (6000 - x)

and its total fat content is 0.0045(6000 - x).

6000 x 0.04 = 0.0045 (6000 - x) + 0.45x

x= 478.1144 kg

So that the flow of cream is 478.1144 kg h-1 and skim milk (6000 - 478.1144) = 5521.8856 kg h-1
