Final answer:
The new flow rate of whole blood in an IV system can be calculated using Poiseuille's law.
Step-by-step explanation:
The given question is asking about the flow rate of a glucose solution being administered with an IV. The initial flow rate is 4.00 cm³/min. If the glucose is replaced with whole blood with the same density but a viscosity 2.50 times that of glucose, we need to calculate the new flow rate.
To find the new flow rate, we can use Poiseuille's law, which states that the flow rate is inversely proportional to the viscosity. Given that the viscosity of whole blood is 2.50 times that of glucose, the new flow rate would be 4.00 cm³/min divided by 2.50, which equals 1.60 cm³/min.
Therefore, the new flow rate when the glucose is replaced by whole blood would be 1.60 cm³/min.
