Chapter 10, Problem 8P

To determine

To Find: The difference in the blood pressure.

Answer to Problem 8P

The difference in the blood pressure is $16464\text{ Pa}$ .

Explanation of Solution

Given info:

Height of the person, $h=1.6\text{ m}$

Density of blood, $\rho =1.05\times {10}^3{\text{ kg/m}}^3$

Formula used:

Write the expression for change in pressure, $\Delta P=\rho \times g\times h$ .

Here, $\rho$ is the density, g is the acceleration due to gravity and h is the height.

Calculation:

Substitute the given values in the above equation,

  $\Delta P=1.05\times {10}^3\times 9.8\times 1.6=16464\text{ Pa}$ .

Conclusion:

Thus, the difference in the blood pressure between the top of the head and bottom of the feet is $16464\text{ Pa}$ .
