Question

The reading shown by the pressure gauge
when connected to oil tank is 600 kPa. the
atmospheric pressure at that location is 98
kPa. What is the absolute pressure of the oil
tank.​

Answer 1

Answer:

If you limp into a gas station with a nearly flat tire, you will notice the tire gauge on the airline reads nearly zero when you begin to fill it. In fact, if there were a gaping hole in your tire, the gauge would read zero, even though atmospheric pressure exists in the tire. Why does the gauge read zero? There is no mystery here. Tire gauges are simply designed to read zero at atmospheric pressure and positive when pressure is greater than atmospheric.
