Signals and Systems Question on Sensors Transducers and Applications
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.
A
RL will decrease by 16 times
B
RL will decrease by 8 times
C
RL will decrease by 4 times
D
RL will decrease by 2 times
Answer
RL will decrease by 16 times
Explanation
Solution
The correct option is (A) : RL will decrease by 16 times.
