Change is the sensitivity of transmitter = Sensitivity of flow measurement
Sensitivity is reduced by 5%.
Since other parameters are constant, hence sensitivity of flow measurement also reduces by 5%.

Explanation:

Given:
- A differential pressure transmitter is used to measure the flow rate in a pipe.
- The sensitivity of the pressure transmitter is reduced by 5% due to aging.
- All other aspects of the flow meter remain constant.

To Find:
- The change in the sensitivity of the flow measurement.

Solution:
The sensitivity of a differential pressure transmitter is a measure of how much output signal it produces for a given change in pressure. In this case, the sensitivity of the pressure transmitter is reduced by 5%, which means it now produces 95% of its original output signal for the same change in pressure.

Since all other aspects of the flow meter remain constant, the change in the sensitivity of the flow measurement can be directly correlated to the change in the sensitivity of the pressure transmitter.

Formula:
Change in sensitivity of flow measurement = Change in sensitivity of pressure transmitter

Calculation:
Change in sensitivity of flow measurement = 5% (reduced sensitivity of pressure transmitter)
= 5% of the original sensitivity

Therefore, the change in the sensitivity of the flow measurement is 5%.

Answer:
The correct answer is option 'b' (5.0%).
