Water is flowing through a channel (lying in a vertical plane) as shown in the figure. Three sections A, B and C are shown. Sections B and Chave equal area of cross section. If `P_(A) , P_(A) `and` P_(C)` are the pressures at A, Sand C respectively then

A

`P_(A)gtP_(B) = P_(C)`

B

`P_(A) lt P_(B) lt P_(C)`

C

`P_(A) lt P_(B) = P_(C)`

D

`P_(A)gtP_(B) gt P_(C)`
