Refer to the drawing of an operating cooling water system (see figure below).
The pump is unable to achieve its rated volumetric flow rate due to cavitation.
Which one of the following will enable the pump to achieve a higher volumetric flow rate before cavitation occurs?
A. Decrease the surge tank water level.
B. Increase the service water flow rate to the heat exchanger.
C. Move the surge tank connection closer to the discharge of the pump.
D. Remove the existing pump motor and install a motor with a higher horsepower rating.
