Pressure at Depth: Density, Specific Weight, Gauge vs Absolute Pressure & Metres of Head
This lesson is part of the course
In this lesson
You turn densities into specific weights, calculate the pressure at six depths in a water tank, convert gauge kPa into absolute bar and express a pressure reading as metres of oil head.
