Please answer the pressure question.

Dear Student,

Please find the solution to your query below:

Given,
Upper blood pressure = 160 cm of Hg
Normal blood pressure = 120 cm of Hg

Now the difference between the blood pressure is
Upper - Normal = 160 - 120 = 40 cm of Hg or 0.4 m of extra pressure
$Pressure = \rho \times g \times h$
​​​​​​P = 13600 x 10 x 0.4
P = 54400 Nm^-2
Thus the extra pressure generated by the heart is 54400 Nm^-2
