Example 3: Water flow<strong>in</strong>g at 4 m/s passes througha Venturi tube as shown. If h = 12 cm, , what is thevelocity of the water <strong>in</strong> the constriction?Bernoulli’s Equation (h 1 = h 2 )P gh½v ½v2 22 1hv 1 = 4 m/sv 2h= 6 cmCancel , then clear fractions:2gh = v 22-v 12v 2ghv 2(9.8 m/s )(0.12 m) (4 m/s)2 2 22 1v 2 = 4.28 m/sNote that density is not a factor.
