Question

gauge pressure =??? (a) absolute pressure +vacuum pressure. (b) atmospheric pressure +absolute pressure. (c) absolute pressure -atmospheric pressure. (d) atmospheric pressure -absolute pressure ​

Answer 1

Actually your que is very important

So what I know that I am telling.

gauge pressure is the pressure relative to atmospheric pressure. Gauge pressure is positive for pressure above atmospheric pressure and negative for pressure below it.

Pabs=Pg+Patm where

Pabs is absolute pressure Pg is gauge pressure Patm is atmospheric pressure.

Absolute pressure is the sum of gauge pressure and atmospheric pressure.

Absolute pressure is zero reference against perfect vacuum. so it is against to gauge pressure +atmospheric pressure. Gauge pressure is also zero reference against ambient atmospheric pressure. So it equal to absolute pressure-atmospheric pressure,negative signs are usually ommited.

Thnks and sorry also because I cant able to explain it properly.

I hope this may help u...
