In the commercial production of sugar (sucrose), the product crystals are washed and centrifugedto partial dryness. the crystals are then sent through a rotary dryer where they are contacted with ahot stream of air that reduces the moisture content from 1: 0wt%to 0: 1wt%. the ratio of wet sugarto inlet air fed to the dryer is 3.3 kg wet sugar/kg inlet air. the inlet air contains 1.5 mole% water.

(a)draw and label theflowchart and do the degree-of-freedom analysis.

(b)taking a basis of 100 kg of wet sugar fed to the dryer, calculate the mass of water and its molefraction in the air leaving the dryer.

it was a fall down when it happens

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.
