I hope everyone will pray for me. Enough talk, let’s get straight to the point; it’s quite simple； The question is as follows: The readings of the pressure gauges used for importing a certain device are 3 Kpa (vacuum) and 67 Kpa (gauge pressure). What are the absolute pressures at these two points? The absolute pressure of 3 KPa is 101 KPa (atmospheric pressure) – 3 KPa = 98 KPa. The absolute pressure of 67 KPa is 101 KPa + 67 KPa = 168 KPa
The pressure difference between the two points should be 164 KPa, right?

Hehe, the path is right under our feet; if we work hard, good results will follow. My answer: 64kpa.
Answer: 98KPa 168KPa
98KPa and 168KPa respectively
