What is the difference between gauge pressure and sealed gauge pressure?
A. Gauge pressure is measured relative to atmospheric pressure, while sealed gauge pressure is measured relative to a perfect vacuum.
B. Gauge pressure is always positive, while sealed gauge pressure can be positive or negative.
C. Gauge pressure is measured inside a container, while sealed gauge pressure is measured outside a container.
D. Gauge pressure is measured relative to atmospheric pressure, while sealed gauge pressure is measured relative to a fixed reference pressure.
Answer:D
