If A pressure gauge reads 16.2 bar what is the pressure in kpa?

16.2 bar = 1,620 kPa


What if the fuel pressure is at 80 psi in an explorer?

Your pressure gauge may be broken....If it fluctuates, then you know its not your gauge, but if your gauge always reads 80, it may need to be replaced.


How does pressure gauge work?

Reverse airflow feels a chamber inside the gauge and reads the pressure equal to the inside of the tyre its that simple. Same for air compressure, when the pressure is applied it seals the valve on the gauge end then back pressure fills the chamber inside the gauge when you release the gauge from the tyre valve the pressure has gone!!


Difference between pressure gauge and manometer?

A manometer is a pressure gauge, "Manometer" reads extremely low pressures that are very close to atmospheric pressures, "pressure gauges" read much larger pressures.

What gauge measures both vacuum and pressure?

Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
