**drwls**, Monday, January 11, 2010 at 10:36pmThe water speed will drop by a factor 1/4 because of the larger pipe area. That follows from the incompressible fluid continuity equation, V * Area = constant. The water speed in the wider section is 3 m/s

Use the change in velocity and the Bernoulli equation to get the change in pressure.

P + (1/2)(density) V^2 = constant

P2 - P1 = (1/2)(water density)(V1^2 - V2^2

Solve for P2.
