Q
The curves apply to an open cooling water system using one single-speed centrifugal pump
discharging through a typical flow control valve.
One of the system curves shows system head loss with the flow control valve 25 percent open. The
other system curve shows system head loss with the flow control valve 100 percent open. The pump
is initially operating with the valve 25 percent open, resulting in a pump flow rate of 800 gpm.
If the flow control valve is subsequently fully opened, pump flow rate through the valve will be
approximately…
A. 400 gpm.
B. 1,200 gpm.
C. 1,600 gpm.
D. 3,200 gpm.
A
1,200 gpm.
