Refer to the drawing in which water is flowing through a convergent-divergent venturi (see figure below). The pipe diameters at P1 and P2 are equal.
Compared to the conditions at the inlet of the venturi (P1), the pressure at the outlet of the venturi (P2) has __________; and water velocity at the outlet of the venturi has __________. (Assume “real” conditions.)
A. remained the same; remained the same
B. remained the same; decreased slightly
C. decreased slightly; remained the same
D. decreased slightly; decreased slightly
