## Main Question or Discussion Point

Can anyone tell me if the reverse of Bernoulli's principal is true, in other words if I go from a smaller diameter pipe to a large pipe does the pressure increase? Applying this to a Venturi tube if I go from a large pipe to a smaller pipe and add an inlet that adds mass due to the suction (pressure differential), then I want to return to the pressure that I originally had do I just need a large diameter pipe than I began with? If this is the case where did the extra energy come from, or is there an energy loss I am missing?
