The drawing shows an intravenous feeding. With the distance of 0.610 m, nutrient solution (ρ = 1010 kg/m3) can just barely enter the blood in the vein. What is the gauge pressure of the venous blood? Express your answer in millimeters of mercury.
The guage pressure at the height h = ρgh
the atmospheric pressure = 1.013•10⁵ Pa
ρgh•760/1.013•10⁵ =1030• 9.8•0.61•760/1.013•10⁵=46.2 mmHg
