Answer:
0.47361
Explanation:
L = Length of cylinder = 1 cm
d = Diameter of cylinder = 0.9 cm
r = Radius of cylinder = [tex]\frac{d}{2}=\frac{0.9}{2}=0.45\ cm[/tex]
h = Hematocrit
A = Area = [tex]\pi r^2[/tex]
The resistivity of blood is given by
[tex]\rho=\frac{1.32}{1-h}-0.79[/tex]
The resistivity of a material is given by
[tex]R=\rho\frac{L}{A}\\\Rightarrow R=\frac{1.32}{1-h}-0.79\times \frac{0.01}{\pi 0.0045^2}\\\Rightarrow h=1-\frac{1.32}{\frac{AR}{L}+0.79}\\\Rightarrow h=1-\frac{1.32}{\frac{\pi 0.0045^2\times 270}{0.01}+0.79}\\\Rightarrow h=0.47361[/tex]
The hematocirt of the blood is 0.47361
