I know to use Bernoulli's Equation and the Equation of Continuity, but I can't figure out how to solve for either velocity variable.

**drwls**, Friday, November 20, 2009 at 2:19amP1 - P2 = (rho/2)(V2^2 - V1^2)= 8000 N/m^2 (Bernoulli equation)

(rho is the fluid density)

6^2*V1 = 4^2*V2, so V2 = (4/9)V1

(from the continuity equation)

Substitute (4/9)V1 for V2 in the first equation and solve for V1

The volume flow rate is (pi/4)D^2*V1

where D = 0.06 m
