You are tasked with designing a drug infusion system to supply a constant rate of liquid to the body. what pressure differential is needed to achieve a flow rate of 0.5 ml/hr if the tube has a diameter of 0.1 cm and a length of 10 cm, and the viscosity of the fluid is 0.66 mpa·s. you can make the same assumption as given for the pressure driven flow in cylinder example above. for this pressure drop, what is the maximum velocity of the fluid?
