Question

When the pressure intensity at a point is more than the local atmospheric pressure, then the difference of these two pressures is called-

• A. Positive gauge pressure
• B. Barometric pressure
• C. Absolute pressure
• D. Negative gauge pressure

Answer 1

Answer:

A. Positive gauge pressure

When the pressure at a point exceeds the local atmospheric pressure, it is called positive gauge pressure. If it is below atmospheric pressure, it is negative gauge pressure or vacuum pressure.
