Given:
fraction of water in wet sugar of m kg by mass,
% of water evapourated from the total water after passing through the evapourator,
a)
amount of wet sugar fed to the evapourator,
Now the mass of water present in the fed amount of sugar:
Now the amount of water leaving from this total amount of water after passing through the evapourator:
i)
So, the fraction of of water leaving the evapourator:
ii)
Now the ratio of kg water vaporized/kg wet sugar leaving the evaporator.:
b)
amount of sugar fed per day,
<u>Now the mass of water in the given amount of sugar per day:</u>
Mass of water vapourized after passing through the evaporator:
Now the mass of water still remaining in the sugar:
is the mass of extra water to be evapourated.
