Question

blood is pumped from the heart at a rate of 5.0l/min into the aorta (radius 1.0cm)determinethethe speed of the blood
bobpursley
volume=area*distance
volume/time=area*distance/time
distance/time=speed=5dm^3/sec /(Pi r^2)

since you units on volume are decimeter, change radius for cm to dm, or r=.1dm
speed=5dm^3/(PI*.1^2 dm^2)
that give you speed in dm/min

now if you want cm/sec, multiply by 10
