What is the pressure of a general pressure cooker?

The pressure in the pressure cooker depends on the diameter of the air hole and the quality of the pressure limiting valve. If the diameter of the air hole is 3mm, the mass of the pressure-limiting valve is 100g, and the pressure generated by the pressure-limiting valve is p = mg/s = 0.1*10/(3.14 * 0.003 2/4).

The maximum pressure of internal water vapor is p1= p+P0 =141542.82+10x105 = 241542.82 pa, which is equivalent to 2.4 pa of atmospheric pressure. At this time, the boiling point of water in the pressure cooker is 125.7 degrees Celsius.
