| Both existing centrifugal cooling water pumps will be replaced by two of a higher GPM. Only one pump is used in normal operation and there will be no modifications to their discharge piping. This is an operational concern since increased velocity will increase pipe erosion. What is the fluid velocity in feet/minute in the discharge piping with new pumps, given the following data? | |
| A) 100.149 ft./min. | |
| B) 112.151 ft./min. | |
| C) 78.719 ft./min. | |
| D) 126.151 ft./min. | |
