Question
Consider ideal flow of water through a pipe with its axis horizontal. A and B are the two points in the same horizontal level (A lies on the upstream), then
- The pressures at A and B are equal for any shape of the pipe
- The pressure are never equal
- The pressure are equal if the pipe has a uniform cross-section
- The pressures at A is always more than that at B
The correct answer is: The pressure are equal if the pipe has a uniform cross-section
Since water flows from A→B, so A is at higher pressure than B.
