Answer :
Final answer:
The correct measurement in kPa for a pressure transmitter reading 20 psi is 137.9 kPa, corresponding to option A.
Explanation:
To convert a pressure from psi to kPa, you can use the following conversion factor: 1 psi = 6.89476 kPa. For a pressure of 20 psi, you multiply by this conversion factor to find the equivalent pressure in kilopascals.
20 psi x 6.89476 kPa/psi = 137.8952 kPa.
Therefore, the correct measurement in kPa for a pressure transmitter reading 20 psi is 137.9 kPa (rounded to one decimal place as provided in the options).
The correct answer from the provided options is A. 137.9 kPa.
