This set of Chemical Process Calculation Multiple Choice Questions & Answers (MCQs) focuses on “Material balances for Multi-Unit System-Sequetial Multiunit System-I”.

1. If the values of Feed 1, 2, 3, 4, and 5 are 10, 20, 30, 40, and 50 moles respectively, what is the total value of D?
a) 100
b) 120
c) 130
d) 150
View Answer

Answer: d
Explanation: D = Feed (1 + 2 + 3 + 4 + 5) = 10+20+30+40+50 = 150.

2. With the values of Feed 1, 2, 3, 4, and 5 as 10, 20, 30, 40, and 50 moles respectively, what is the value of D when Feed 5 is inverted?
a) 50
b) 100
c) 150
d) 200
View Answer

Answer: a
Explanation: D = Feed (1 + 2 + 3 + 4 – 5) = 10+20+30+40−50 = 50.

3. Given the feed values of 10, 20, 30, 40, and 50 moles for Feed 1, 2, 3, 4, and 5 respectively, what is D when Feed 4 is inverted?
a) 100
b) 110
c) 120
d) 130
View Answer

Answer: b
Explanation: D = Feed (1 + 2 + 3 – 4 + 5) = 10+20+30−40+50 = 110.

4. If Feed 1, 2, 3, 4, and 5 are 10, 20, 30, 40, and 50 moles respectively, what is the value of D when Feed 3 is inverted?
a) 90
b) 100
c) 150
d) 200
View Answer

Answer: a
Explanation: D = Feed (1 + 2 – 3 + 4 + 5) = 10+20−30+40+50 = 90.

5. With feeds set at 10, 20, 30, 40, and 50 moles for Feed 1, 2, 3, 4, and 5 respectively, can D be calculated if Feed 2 is inverted?
a) 100
b) 110
c) 120
d) Not possible
View Answer

Answer: d
Explanation: It is not a possible case.

6. If Feed 1, 2, 3, 4, and 5 are 10, 20, 30, 40, and 50 moles respectively, what is the value of D when Feed 1 is inverted?
a) 100
b) 110
c) 120
d) 130
View Answer

Answer: d
Explanation: D = Feed (-1 + 2 + 3 + 4 + 5) = −10+20+30+40+50 = 130.

7. If Feed 1, 2, and 3 are 10, 20, and 30 moles respectively, what would C=Feed (1+2−3) equal if Feed 3 is inverted?
a) 0
b) 80
c) 90
d) 100
View Answer

Answer: c
Explanation: C = Feed (1 + 2 – 3) = 10+20−30 = 90.

8. When Feed 1, 2, 3, and 4 are valued at 10, 20, 30, and 40 moles, what is the value of B=Feed (1+2−3+4) with Feed 3 inverted?
a) 40
b) 80
c) 90
d) 100
View Answer

Answer: d
Explanation: B = Feed (1 + 2 – 3 + 4) = 10+20−30+40 = 100.
