How High Should the IV Bag Be to Ensure Fluid Flow into the Vein?

[thedark_master]

An IV is connected to a patient's vein. The blood pressure in the vein has a gauge pressure of 18 mm Hg. At least how far above the vein must the IV bag be hung in order for fluid to flow into the vein? Assume the fluid in the IV has the same density as blood (use 1060 kg/m3 for the density of blood).



I am not sure what equations i should use.

Look for an equation relating pressure to depth in a fluid.
