Question

A glucose solution being administered with a flow rate of 4 cm/min. What will the new flow rate be if the glucose is replaced by blood having the same density but a viscosity 2.5 times that of the glucose? other factors remain constant.​

Answer 1

Answer: 1.60 cm3 _ min

Explanation:

First we have assumed that there is laminar flow for both fluids, in order for us to be able to use Poiseuille’s law. Then, we write this law for this case in which the blood is flowing. Afterwards, we can rearrange the equation so that we can replace the expression in the bracket for Qglucose.
