A liquid medicine is injected into a patient from an IV bag
elevated h = 0.800 m above the needle, see figure. The needle is
placed horizontally. The needle is 3.00 cm in length and 0.400 mm
in diameter. Assume the average gauge pressure inside the vein is
1.28 x 10^3 Pa; the viscosity of the medicine is 2.00 x 10^-3 Pa*s;
and the density of the medicine is 1.05 x 10^3 kg/m^3 .
(1) Calculate the pressure difference between the input and output
of the needle.
(2) Calculate the time it takes to inject 525 cm^3 of the medicine
into the vein.

An intravenous drip bag has a volume of, 500 cm3 (0.5 ml). Assume it empties through a 20-gauge needle (diameter of about 0.6mm) with a length of 2 inches (5.08 cm) and we want it to empty in 30 minutes. How high must the bag be hung? Assume the viscosity of the fluid is 0.005 Pa s, the density of water is 1000 kg m-3, and the pressure in the vein is 20 mm-Hg (or 2666 Pa gauge pressure).

A patient is to be injected with 0.4 L of an electrolyte solution in 1/2 an hour. Assuming that the solution is elevated by 1 m above the arm, and that the hydrostatic pressure alone is used to push the solution into the arm (as is typical of an IV), and assuming that the needle itself is 2.5 cm long, what inner diameter must the needle have to allow this? (use ?η=1×10−31×10−3 Ns/m22 and ?ρ=1000 kg/m33; the values for water....

A patient in the hospital is receiving a saline solution through a needle in their arm. The needle is 2.20 cm long, horizontal, with one end in a vein in the arm, and the other end attached to a wide tube that extends down from the bag of solution, which hangs from a pole so that the fluid level is 90.0 cm above the needle. The inner radius of the needle is 0.250 mm. The top of the fluid is...

A glucose solution of viscosity 2.2 × 10−3 N⋅s/m2 and density 1030 kg/m3 flows from an elevated open bag into a vein. The needle into the vein has a radius of 0.20 mm and is 3.0 cm long. All other tubes leading to the needle have much larger radii, and viscous forces in them can be ignored. The pressure in the vein is 1000 N/m2 above atmospheric pressure. Determine the pressure relative to atmospheric pressure needed at the entrance of...

At the hospital, a patient often receives fluids via an intravenous (IV) infusion. A bag of fluid is held at a fixed height above the patient’s body. The fluid then travels down a large diameter, flexible tube to a catheter – a short tube with a small diameter – inserted into the patient’s veins. 1.0 L of saline solution, with a density 1020 kg/m3 and a viscosity of 1.1 x 10-3 Pa s, is to be infused into a patient...

A liquid chemical is pumped from a storage tank open to the atmosphere, into a reactor with pressure of 2.0 atm gauge above the liquid level. The liquid density is 1200 kg/m3 and viscosity is 1.45 cP. The required volumetric flow rate is 1.25 x 103 m/s. The pipeline is 100 m long in total, made of commercial steel pipe, 2 in. size and Schedule 40. The gate valve is wide open. 10 m Reactor Calculate: (a) The discharge velocity...
