Question

Flow rate of blood through a capillary of cross-sectional area of 0.25 m2 is 100 c m3 / s . The velocity of flow of blood is (A) 1mm/s (B) 0.2 m m / s (C) 0.3 m m / s (D) 0.4 m m / s

For the blood flow in capillary, Volumetric flow rate = velocity Ã area of cross-section v=(Q/A)=(100 × 1 0- 6/0.25) Q=Av v=400 × 10- 3 m m / s=0.4 m m / s

Q. Flow rate of blood through a capillary of cross-sectional area of $0.25 m^{2}$ is $100 c m^{3} / s$ . The velocity of flow of blood is

$1 mm / s$

$0.2 mm / s$

$0.3 mm / s$

$0.4 mm / s$

For the blood flow in capillary, Volumetric flow rate = velocity × area of cross-section
$v = \frac{Q}{A} = \frac{100 \times 1 0 ^{- 6}}{0.25}$
Q=Av
$v = 400 \times 1 0^{- 3} mm / s = 0.4 mm / s$

Q. Flow rate of blood through a capillary of cross-sectional area of 0.25m2 is 100cm3/s . The velocity of flow of blood is

1mm/s

0.2mm/s

0.3mm/s

0.4mm/s
