Pressure Units: Gauge vs Absolute, bar/kPa/psi & the Compression Ratio
This lesson is part of the course
In this lesson
You bring six gauge readings in bar, kPa and psi onto one scale, add the atmosphere to get absolute pressure, calculate the compression ratio and turn a charged tank into litres of free air.
