Two pumps can operate independently at heads H1, H2 and discharges Q1, Q2, respectively. If the pumps are connected in parallel, then what are the resulting discharge (Q) and head (H)?
- a)Q = Q1 + Q2; H = H1 + H2
- b)Q = Q1 - Q2; H = H1 + H2
- c)Q = Q1 = Q2; H = H1 = H2
- d)Q = Q1 + Q2; H = H1 = H2
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Two pumps can operate independently at heads H1, H2and discharges Q1, ...
Pumps in Parallel:
Same Head: H = H1 = H2
Add the discharge: Q = Q1 + Q2
Pumps in Series:
Same Discharge: Q = Q1 = Q2
Add the heads: H = H1 + H2

Two pumps can operate independently at heads H1, H2and discharges Q1, ...
Explanation:
When two pumps are connected in parallel, they operate independently and their discharges add up while the heads remain the same. Let's break down the given options and understand why option D is correct.
a) Q = Q1 * Q2; H = H1 * H2:
This option suggests that the resulting discharge (Q) is the product of the individual discharges (Q1 and Q2) and the resulting head (H) is the product of the individual heads (H1 and H2). However, when pumps are connected in parallel, the discharges add up, they do not multiply. Hence, this option is incorrect.
b) Q = Q1 - Q2; H = H1 * H2:
This option suggests that the resulting discharge (Q) is the difference between the individual discharges (Q1 and Q2) and the resulting head (H) is the product of the individual heads (H1 and H2). Again, this option is incorrect because the discharges add up when pumps are connected in parallel, not subtracted.
c) Q = Q1 = Q2; H = H1 = H2:
This option suggests that the resulting discharge (Q) is equal to both individual discharges (Q1 and Q2) and the resulting head (H) is equal to both individual heads (H1 and H2). This is partially correct as the discharges are indeed equal when pumps are connected in parallel. However, the heads remain the same and do not change. Therefore, the correct answer must have H = H1 = H2, but this option does not mention that. Hence, this option is also incorrect.
d) Q = Q1 + Q2; H = H1 = H2:
This option suggests that the resulting discharge (Q) is the sum of the individual discharges (Q1 and Q2) and the resulting head (H) is equal to both individual heads (H1 and H2). This is the correct option because when pumps are connected in parallel, the discharges add up and the heads remain the same. Therefore, the correct answer is option D.
To summarize, when two pumps are connected in parallel, the resulting discharge is the sum of the individual discharges, and the resulting head remains the same as the individual heads.

This option suggests that the resulting discharge (Q) is the sum of the individual discharges (Q1 and Q2) and the resulting head (H) is equal to both individual heads (H1 and H2). This is the correct option because when pumps are connected in parallel, the discharges add up and the heads remain the same. Therefore, the correct answer is option D.
