Question: how to find percentage of water in milk?
Answer: The first 2 formulae, which express the amount of water in g/100 g watered milk (Y), are: Winter's formula, Y = 100( DELTA T1 - DELTA T2)/ DELTA T1; and the Elsdon & Stubbs formula, Y = (100 - D2)[( DELTA T1 - DELTA T2)/ DELTA T1], where D2 is the TS content of the milk after watering.
