Blood is flowing at the rate of `200cm^(3)s^(-1)` in a capillary of cross sectional area `0.5m^(2)`. The velocity of flow in `mms^(-1)` is:

Options

A. 0.1
B. 0.2
C. 0.3
D. 0.4

Answer

D

Explanation

Rate of flow of blood,
`V=Av`
or `v=(V)/(A)=(200cm^(3)s^(-1))/(0.5xx10^(4)cm^(2))`
`=0.04cms^(-1)`
`=0.4mms^(-1)`
