A drug is being delivered into a patient’s arm at a rate of 319 mL/min. This drug has a density of 1050 kg/m^3 and viscosity of 8.90×10^–4 Pa.s . Determine its flow type when its move from a syringe through a needle with an internal diameter of 1 mm?

Medical You inject your patient with $2.50 \mathrm{~mL}$ of medicine. If the inside diameter of the 31-gauge needle is $0.114 \mathrm{~mm}$ and the injection lasts $0.650 \mathrm{~s}$, determine the average speed of the fluid as it leaves the needle.
In intravenous feeding, a needle is inserted in a vein in the patient's arm and a tube leads from the needle to a reservoir of fluid (density 1050 $\mathrm{kg} / \mathrm{m}^{3} )$ located at height $h$ above the arm. The top of the reservoir is open to the air. If the gauge pressure inside the vein is 5980 $\mathrm{Pa}$ , what is the minimum value of $h$ that allows fluid to enter the vein? Assume the needle diameter is large enough that you can ignore the viscosity (see Section 14.6 ) of the fluid.
Blood is placed in a bottle 1.40 m above a 3.8-cm-long needle, of inside diameter 0.40mm, from which it flows at a rate of 4.1 cm$^3/$min. What is the viscosity of this blood?
