Water is flowing through a pipe whose cross-sectional area at point A is larger than the cross-sectional area at point B.The reading on a pressure gauge connected to the pipe at point A will be _____________ the reading on a pressure gauge connected to the pipe at point B.
A)the same as
B)higher than
C)lower than
D)unrelated to

According to Bernoulli's principle, as the cross-sectional area of a pipe decreases, the velocity of the fluid increases and the pressure decreases. Therefore, the reading on the pressure gauge connected to point A will be higher than the reading on the gauge connected to point B.
