A pipe has a cross sectional radius of 6.00 cm and is carrying water moving at .380 m/sec. If the pipe narrows to a radius of 3.50 cm, what will be the speed of the water in the narrow segment? What is the flow rate in each segment?
thank you!!!!!!!

lAW OF CONTINUITY:
area1*speed1=area2*speed2
speednarrow=PI(6^2)*.380/(.350^2)
volume flow rate=speed*area do that for both sides.

oops, add a PI in the denominator of the law of continuity, area=pI*radius^2
