| The feed water heater shown in the illustration was designed to maintain the required feed water outlet temperature with an approximate 10" (25.4 cm) Hg shell vacuum. If the shell vacuum is increased to approximately 16" (40.64 cm) Hg vacuum, the __________ . |
| A) overall plant operating efficiency will increase |
| B) vacuum in the main condenser will drop as the feed heater shell vacuum increases |
| C) feed water outlet temperature will decrease |
| D) flow rate of condensate to the feed heater will increase |
