The system is exactly, specified problem and the values of all the unknows will be determined unkowns will have a unique value.
<u>Explanation:</u>
given informtion:
pineapple:
water = 80 % = 0.8
solids = 20% = 0.2
pineapple : sugar = 1:5
jam:
water = 30% = 0.3
solids and sugar = 70%
basis: 1 kg pineapple
therefore, sugar = 5 kg
the process flow sheet is as:
As per the figures shown in the attached file, DOF = 0, thus the system is exactly, specified problem and the values of all the unknows will be determined unkowns will have a unique value.
Answer:
a) 154054 gals
b) 20850 lb/day
c) 0.7392hr
d) 2.466day^-1
e) 7.23 lb/day-1000 ft^3
Explanation:
a)
b)
Dry mass = 5 MGD * (0.20) * (2500 mg/l) * 8.34 = 20850 lb/day
c)
Aeration period Q =
d)
e)
BOD loading =
