Refer to the drawing of a steam condenser, hotwell, and condensate pump (see figure below).
Given the following initial conditions:
- Condenser pressure is 1.2 psia.
- Condensate temperature is 96°F.
- Hotwell level is 10 feet above the condensate pump suction.
Which one of the following will provide the greatest increase in NPSH available to the condensate pump?
(Assume that condenser pressure does not change.)
A. Hotwell level decreases by 6 inches.
B. Hotwell level increases by 6 inches.
C. Condensate temperature decreases by 6°F.
D. Condensate temperature increases by 6°F.
