Answer

0.6 atm.

Work Step by Step

Use equation 10–3b to calculate the change in blood pressure, then divide by atmospheric pressure to express the answer as a fraction of atmospheric pressure. $$\Delta P = \rho_{blood} g \Delta h$$ $$\frac{\Delta P}{P_o} = \frac{\rho_{blood} g \Delta h}{1.013\times10^5\;Pa}= \frac{(1.05\times10^{3}\;kg/m^3) (9.80\;m/s^2) (6\;m)}{1.013\times10^5\;Pa}=0.6$$
