I thought annubar and venturi were synonymous. Create a constriction in the flow path and apply Bernoulli's Principle: ~where the velocity of a fluid is high the pressure is low and, where the velocity of a fluid is low the pressure is high~ The change in pressure is half the mass times the velocity squared (Bernoulli's Equation). How is it broken? Something clogged up? On May 10, 2016 3:40 PM, "Karen Lesko" <[email protected]> wrote:
