Answer:

Explanation:

From the given information; the diagram below shows a clearer understanding.

The blood pressure in the brain [tex]P_{brain} = P_{heart} - \delta ( a - g ) h[/tex]

= 13300 - 1060 (12-9.81) 0.35

=  13300 -  1060 (2.19) 0.35

= 13300 - 812.49

= 12487.51  Pa

The blood pressure in the feet [tex]P_{feet} = P_{heart} + \delta (a + g) h[/tex]

= 13300 + 1060 (12 + 9.81) 1.45

= 13300 + 1060( 21.81 ) 1.45

= 13300 + 33521.97

= 46821.97 Pa

Answer:

  • The blood pressure in the brain = [tex]12487.51 pa[/tex]
  • The blood pressure in the feet = [tex]46821.97pa[/tex]

Explanation:

[tex]P_brain = P_heart - y(a - g)h\\\\P_brain = 13300 - 1060 (12-9.81)0.35\\\\P_brain = 12487.51 pa\\\\[/tex]

[tex]P_feet = P_heart + y(a+g)*h_r\\\\P_feet = 13300 + 1060(12+9.81)*(1.8-0.35)\\\\P_feet = 46821.97pa[/tex]
