Refer to the drawing of two identical pressure vessels with identical relief valve protection (see figure below).
Both vessels have been pressurized to 50 psig and then isolated.
Vessel A is completely filled with water at 150°F.
Vessel B is in a saturated condition with one-half steam (100 percent quality) and one-half water (0 percent quality) by volume.
If both relief valves fully open simultaneously, the faster pressure reduction will occur in vessel __________; and if both relief valves close at 40 psig, the greater mass loss will have occurred in vessel __________.
A. A; A
B. A; B
C. B; A
D. B; B
