**Anonymous**, Saturday, January 15, 2011 at 2:39pmA2 = A1/4, so you know A1v1 = A2v2

A1v1 = A1/4v2, cancel out the A1's

v1 = 1/4 v2

v2^2 = 16v1^2 --- eqn 1

change in pressure = (rho)gh = 3332 N/m^2

3332 = 1/2(rho)(v2^2 - v1^2)

3332 = (1/2)(1000)(v2^2 - v1^2)

v2^2 = 6.664 + v1^2 --- eqn 2

16v1^2 = 6.664 + v1^2

v1 = 0.6665 m/s

.... I hope this is right.
