Homework Help: Speed of blood in aorta

  1. Nov 1, 2006 #1
    If the average volume flow of blood through the aorta is 9 × 10-5 m^3/s and the cross-sectional area of the aorta is 3.1 × 10-4 m^2, what is the average speed of blood in the aorta in cm/s?

    Looking through my lecture notes I do not see any equations relating volume of a liquid/area/velocity. How would I begin to work out a simple problem such as this?

    I would suggest looking at the units of the volume flow of blood, and the cross sectional area of the aorta. Can you get m/s?

    The flow equals the product of the cross section and velocity, unless I'm missing someting here.
