A Liquid, Such as Water, with a Low but Not

Multiple Choice

A liquid, such as water, with a low but not negligible viscosity is flowing from A to C with no turbulence through the horizontal tube, as shown in the figure. The cross-sectional area at A is equal to that at C. Which of the following is observed?

A) The pressure at A is the same as the pressure at C, and this pressure is smaller than the pressure at B.
B) The pressure at A is somewhat larger than that at C, and the pressures at both A and C are larger than the pressure at B.
C) The pressures at A and C are the same, and this pressure is larger than the pressure at B.
D) The pressure at A is larger than the pressure at B, which is larger than the pressure at C.
E) None of these is observed.
