100 cm^3/s = 0.25 m^2 * (100cm/m)^2 * v cm/s
v = 100/(100^2 *.25) = 1/25 = 0.04 cm/s = 0.4 mm/s
The total cross-sectional area of all capillary of a certain person’s circulatory system is 0.25 m2. If the blood flows through the system at the rate of 100 cm3/sec, the velocity of the blood in the capillaries is
0.4 mm/s. use Q= AV.
0.04mm/s
0.025 mm/s
250m/s
400 mm/s.
