NARROW PART.  BECAUSE P=F/A.  A IS SMALL SO P IS MORE.........................

in a non uniform pipe , the wider part will be under more pressure. as we reduce the area of cross section, the velocity of the water flowing through that part of the tube is very high , so pressure is very less.

In the wider part the fluid flows at a slower speed, so the pressure is maximum 11 years ago

Use less exclamation marks next time. The answer is found applying bernaullis theorem which states that P + dgh + 1/2dv^2 is constant along a streamline. Where d is the density. Now we know that velocity is higher when the area is less. Because V.A is constant. So applying this in bernaullis, Pressure will be highest when the velocity is lowest. So your answers are B & C. (since velocity is low in the wide part too)

equation of continuity = a1v1 = a2v2

from above eq speed of liquid will be more where pipe is narrow  ....

from bernaulis mass conservation : dv12/2 + p1 = dv22 + p2

from above equation it is clear that if speed is increased then

pressure is deceased ....

so for increasing pressure , speed should be low , tube should be wider ....

option b,care correct

in a pipe, liquid flows from high pressure region to low pressure region.

so, pressure is more at the starting of the pipe.
