A patient is to be given a blood transfusion. The blood is toflow through a tube from a raised bottle to a needle inserted inthe vein (Figure 1). The inside diameter of the 31 mm long needleis 0.60 mm , and the required flow rate is 2.2 cm^3 of blood perminute.

How high "h" should the bottle be placed above the needle?Use ρblood = 1.05×10^3kg/m^3, ηblood =4.0×10−3Pa⋅s. Assume the blood pressure is 80 torr aboveatmospheric pressure.

be h
