In hemodynamics, blood flow through the cardiovascular system
can be modeled as an electric circuit in which the blood serves as
electricity, the blood vessels as resistive wires, and the heart as
a battery (see Figure 1).
Figure 1 Cardiovascular circuit model
Ohm’s law states that the voltage drop ΔV across each element,
the current I flowing through it, and its electrical
resistance R are related by ΔV = IR. In a blood vessel, pressure
difference between one vessel and...

A patient is to be given a blood transfusion. The blood is to flow through a tube from a raised bottle to a needle inserted in the vein (Figure 1). The inside diameter of the 34 mm long needle is 0.90 mm , and the required flow rate is 3.2 cm3 of blood per minute. How high h should the bottle be placed above the needle? Use ρblood = 1.05×103kg/m3, ηblood = 4.0×10−3Pa⋅s. Assume the blood pressure is 66 torr...
