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 24 mm long needle is 0.88 mm , and the required flow rate is 2.6 cm3 of blood per minute. Express your answer using two significant figures. How high h should the bottle be placed above the needle? Use ρblood = 1.05×103kg/m3, ηblood =...
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...
