Blood is pumped from the heart at a rate of 5L/min into the aorta of radius 2.0cm. Assuming that the density of blood 1x103 kg/m3 .Determine the velocity of blood through
the aorta

  • Physical Science -

    Q=vA
    Q=5L/min=8.3e-5 m^3/sec
    A= pi*r^2=3.14*4*10^-4=0.001256 m2
    v=Q/A
    v=8.3e-5/0.001256 = 0.006m/sec = 0.6cm/sec
