Answer 2

The gauge pressure when the absolute pressure on a system is 2 bar will be 0.967 bar.

What is absolute pressure?

• Pressure of perfect vacuum.
• P absolute = P gauge + P atmospheric.

What is gauge pressure?

• The pressure of the system relative to the atmospheric pressure.
• It can have both positive and negative values.

The value of atmospheric pressure is 1.033 bar.

Using the relation,

P absolute = P gauge + P atmospheric.

2 bar  = P gauge + 1.033 bar

P gauge = 2-1.033 bar.

P gauge = 0.967 bar.
