When the pressure intensity at a point is more than the local atmospheric pressure, then the difference of these two pressures is called- Correct Answer Positive gauge pressure
Explanation:
- The pressure is measured relative to atmospheric pressure, pressure above atmospheric pressure is positive gauge pressure and pressure below atmospheric pressure is negative gauge pressure also known as vacuum pressure.
- i.e. PA - Patm → positive gauge pressure
- Patm - PB → negative gauge pressure
- Absolute pressure is sum of gauge pressure and atmospheric pressure.
