Answer:
11320.63 Pa
Explanation:
[tex]P_2[/tex] = Pressure the heart is pumping at = [tex]1.6\times 10^4\ Pa[/tex] (assumed)
[tex]\rho[/tex] = Density of blood = 1060 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
h = Height = 0.45 m
From Bernoulli's equation we have
[tex]P_1=P_2-\rho gh\\\Rightarrow P_1=1.6\times 10^4-1060\times 9.81\times 0.45\\\Rightarrow P_1=11320.63\ Pa[/tex]
The pressure in the artery is 11320.63 Pa
