Fluid Flow; Bernoulli's Equation

  1. Sep 8, 2009 #1
    1. The problem statement, all variables and given/known data

    Using the data of Example 10-11, calculate the average speed of blood flow in the major arteries of the body, which have a total cross-sectional area of about 2.0cm2

    2. Relevant equations

    well... Actually, I don't know how to solve this problem.
    The Example 10-11 gives some of datas.

    "The blood returns to the heart via the veins. The radius of the aorta is about 1.2cm, and the blood passing through it has a speed of about 40cm/s. A typical capillary has a radius of about 4 x 10-4cm, and blood flows through it at a speed of about 5 x 10-4 m/s.

    3. The attempt at a solution

    I do now know what should I use equation first, so would you explain detail to me to learn how to solve this problem easily. Please answer the questions!!!
