Answer:
The dryer evaporate 200 - 24.74 kg of water per hour
To remove 1kg of water it need 3000 K J
So to remove, 175.26 Kg
it need 5.257x KJ of heat per hour.
Explanation:
In one hour, the amount of sugar entering = 1000 kg
w.b moisture content is defined as,
weight of water / weight of water + weight of dry
/ + x 100
+ = 1000 kg when entering
it has 20% moisture content when entering
= 0.2 x 1000 = 200 kg
when leaving it has 3% moisture content then weight of dry material
= 1000 - 200 = 800 Kg
= 0.03
= 0.03
= 0.03 x + 0.03 x 800
= 24.74 kg
When leaving the dryer, the crystals has total weight of the water = 24.74 kg per hour.
The dryer evaporate 200 - 24.74 kg of water per hour
To remove 1kg of water it need 3000 K J
So to remove, 175.26 Kg
it need 5.257x KJ of heat per hour.
Answer:
Explanation:
Assuming the roof is origin and UP the positive direction
d = ½at²
d = ½(-9.8)2.7²
d = -35.721
d = -36 m
It could be the third and the first one.
