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 25 mm long needle is 0.72 mm , and the required flow rate is 3.0 cm³ of blood per minute.

How high h should the bottle be placed above the needle? Use blood = 1.0510³kg/m³, blood = 4.010³Pas. Assume the blood pressure is 78 torr above atmospheric pressure.

Express your answer to two significant figures and include the appropriate units.

I was hoping to get an explanation step-by-step on how to solve this and not just the answer since I don't even know how to approach this. Thanks!
