Answer to Question #186168 in Physics for Will

Question

In order to force intravenous fluid into a patient's veins, the gauge pressure in the feed line at the needle must be +16 kPa.

If the fluid has a density of 1050 kg m⁻³, how high must the bag be raised in order to ensure the fluid goes into the patient's veins?

Answer 1

$$P=\rho gh\\16000=(1050)(9.8)h\\h=1.55\ m$$
