Answer :
Final answer:
The correct answer is C. 2 psi Tests requiring a pressure measurement of greater than 10 psi but less than or equal to 100 psi should utilize a testing gauge with increments of 1 psi or less for accurate pressure readings.
Explanation:
The student's question appears to be about the appropriate gauge division for pressure measurement in a testing scenario where the pressure range is greater than 10 psi but less than or equal to 100 psi.
The correct answer for the gauge increments in this range would likely be B. 1 psi. It is important for such gauges to have a sufficiently fine resolution to accurately measure pressures within the specified range without being unnecessarily fine-grained.
Pressure gauges and manometers are commonly used to measure gauge pressure, which is the pressure relative to atmospheric pressure. Examples provided discuss various instances where pressure is measured, such as in vacuum-packed jars, scuba tanks, and when discussing the behavior of fluids in different pressure conditions.
The testing gauge that should be used for tests requiring a pressure greater than 10 psi but less than or equal to 100 psi should have increments of 1 psi or less.
