Water passes through a closed piping system starting at point 1 and exits to the atmosphere at the highest point near point 4. The pipe is small at point 1 but then widens out to a constant radius for the rest of the pipe.

(A) Rank the velocity of the water in the pipe at the four locations from greatest to least. Justify your answer.

(B) Calculate the pressure in the pipe at the four points from greatest to least. Justify your answer.
