Question
Intravenous infusions are usually driven by gravity by hanging the fluid bottle at
sufficient height to counteract the blood pressure in the vein and to force the
fluid into the body. The higher the bottle is raised, the higher the fluid flow rate
will be. a) If it is observed that the fluid and the blood pressures balance each
other when the bottle is 1.2 m above the arm level, determine the gage pressure
of the blood. b) If the gage pressure of the fluid at the arm level needs to be 20
kPa for sufficient flow rate, determine how high the bottle must be placed. Take
the specific gravity of the fluid to be 1.02.
