A physician judges the health of a heart by measuring the pressure with which it pumps blood.
If the physician mistakenly attaches the pressurized cuff around a standing patient's calf (about 0.82 m below the heart) instead of the arm (Figure 1), what error (in Pa) would be introduced in the heart's blood pressure measurement?
Express your answer using two significant figures.
The average density ρ of blood is known to be 1060 kg/m3
The difference in height Δh is given as 0.70 m
The error in the measurement of pressure is calculated as,
Here g is the acceleration due to gravity.
Substitute 9.8 m/s2 for g, 1060 kg/m3 for ρ, 0.70 m for &D...
