Question: An engineer sets the pressure in a supply tank using a very accurate manometer as a guide and then reads the output of a 20-psig

An engineer sets the pressure in a supply tank using a very accurate manometer as a guide and then reads the output of a 20-psig pressure gauge attached to the tank as 10.2 psig. Sometime later she repeats the procedure and obtains values of 10.4 and 10.3 psig. What can she say about the gauge’s
Precision?
Accuracy?
Resolution?
Repeatability?
