For the pressure conditions under standard conditions, the standard atmospheric pressure is used both domestically and internationally, namely 101.325 kPa, while the temperature is set at 0°C. The volume of 1 m3 measured under these conditions is referred to as 1 standard cubic meter, or simply 1 std m³. My question is: does this standard atmospheric pressure of 0.1 Mpa correspond to the 0.1 MPa shown on a pressure gauge? Is it still the case that the absolute pressure is 0.1 MPa, while the gauge pressure shows 0 MPa? ? ?
One standard atmosphere is an absolute pressure of 0.10133 MPa and a gauge pressure of 0 MPa
The gauge pressure should read 0, and the absolute pressure is 0.1 MPa
The absolute pressure is 0.1 Mpa, and the gauge pressure is 0
