Intravenous therapy usually is 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 flow rate of the fluid 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 density of the fluid to be 1020 kg/m3.

Intravenous therapy usually is 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 flow rate of the fluid
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
density of the fluid to be 1020 kg/m3.
