Absolute Pressure vs Gauge Pressure - Fluid Mechanics - Physics Problems

This physics video tutorial provides a basic introduction into absolute pressure and gauge pressure. The gauge pressure is the difference between the absolute pressure and the atmospheric pressure. A positive gauge pressure means the absolute pressure is above the atmospheric pressure. A negative gauge pressure means the absolute pressure is less than the atmospheric pressure. This fluid mechanics video contains plenty of practice problems. This video explains how to calculate the gauge pressure of a two fluid mixture such as oil and water.
