Question
. You are designing a small implantable microfluidic pump for the continuous delivery of a drug. The pump is a two compartment cylindrical chamber; one compartment containing the drug dissolved within a solvent and the other compartment is the pump engine. These two compartments are separated by a movable piston that pushes on the drug compartment as the pump engine operates. At the other end of the drug compartment there is an exit tube through which the drug solution flows. The exit tube of the pump through which the drug leaves the pump has an internal diameter of 10 m and a total length of 15 cm. What gauge pressure is needed (mmHg) within the drug compartment to maintain a flow rate of the drug solution of 350 micrograms day–1? You may assume that the drug solution has a density of 1 g cm–3 and a viscosity of 3 cP.
Explanation / Answer
The answer of following question is as follows.
The guage pressure needed is 23mm of hg.
While the density is 45gm/cm^3
