1.	Water is flowing through a long horizontal tube. Let P_(A) and P_(B) be the pressure at two points A and B of the tube.
Answer» <P>`P_(A)` must be equal to `P_(B)` `P_(A)` must be greater than `P_(B)` `P_(A)` must be smaller than `P_(B)` `P_(A)=P_(B)` only in the CROSS sectional AREA at A and B are equal Answer :D
