Question:
In a catheter-sensor system to measure blood pressure (P) as shown in the below figure, the liquid resistance (RL) of the catheter is due to friction between shearing molecules flowing through the catheter. Which of the following is TRUE for RL if only the radius of the catheter is doubled. Assume that the pressure difference across the catheter segment is fixed.
