The container of liquid is raised 1.20 m above the patient's arm where the fluid enters his veins. Question: What is the pressure this fluid exerts on his veins, expressed in millimeters of mercury?

Explanation / Answer

= 1035 kg/m3 ; h = 1.2 m; g = 9.81 m/s2

Pressure is simply, P = g h. The answer is in pascals. Convert to mm Hg by using the conversion factor

1 mm Hg = 133.3 Pa
