Blood flow through vessel A, 1 mm in diameter, occurs with a 10
kPa pressure gradient from one end to the other. Blood flow through
vessel B, 2 mm in diameter, occurs with a 1 kPa pressure gradient
from one end to the other. Other conditions are identical. Compared
to vessel A, blood flow in vessel B is
a.
1/10 as fast
b.
1.6 times faster
c.
16 times slower
