Question

Blood is flowing at the rate of 200 cm³/s in a capillary of cross-section area 0.5 m² . The velocity of flow is mm/s is

• A. 0.2
• B. 0.3
• C. 0.4
• D. 0.1

Answer 1

The correct option is C

0.4

From the equation of continuity (av = constant), we have

0.5 V = 200 X 10^-6

V = 4 X 10^-4 m/s

V = 0.4 mm/s.
