Fluid Dynamics Question
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. The inside diameter of the 4.0 cm long needle is 0.40 mm and the required flow rate is 4.0 cm3 of blood per minute. How high should the bottle be placed above the needle?
The n value is 4*10^-3
the density is 1.06*10^3
these values are in SI units
The professor wrote to assume blood pressure is 2400 Pa over atmospheric pressure. However, I do not know how to use this information.
