Answer: v = 14 cm/s
Explanation:
Using the formula Blood Flow = Change in pressure/Resistance
Mathematically represented as Q = P/R
where P = 44 mmHg, R = 1 mmHg·s/ml
Q = (44/1 ) ml/s
Q = 44 ml/s or 44 cm^3/s
Using the formula Velocity = blood flow/cross sectional area
Mathematically represented as v = Q/A
where r = 1 cm, A = π·r^2 = π x 1 x 1 = 3.142 cm^2
1 ml = 1 cm^3 , this implies that Q = 44 ml/s = 44 cm^3/s
v = (44/ π) cm/s
v = 14 cm/s
I hope this is clear?
