Refer to the drawing of a cooling water system and the associated pump/system operating curves (see
figure below).
Pumps A and B are identical single-speed centrifugal pumps, and only pump A is operating. If pump
B is started, after the system stabilizes system flow rate will be...
A. twice the original flow.
B. the same as the original flow.
C. less than twice the original flow.
D. more than twice the original flow.
ANSWER: C. Can you please provide evidence why the answer is C?
COOLING WATER SYSTEM OPERATING CURVES
Expert Answer
In the given scenario, we have two identical single-speed centrifugal pumps, A and B, where only pump A is initially operating.The question asks about the system flow rate after pump B is started.To understand why the answer is C (less than twice the original flow), we need to analyze the operating curves of the pumps and the behavior of the system.PLEASE REFER TO THE SOLUTION IN THIS STEP.
