This document summarizes key concepts from Lecture 2 of MET 306 Fluid Mechanics: 1) It discusses pressure at points in a fluid at rest, explaining that pressure is independent of direction and depends only on depth. 2) It presents the basic equation for pressure as a function of depth and defines terms like incompressible and compressible fluids. 3) It describes different types of pressure measurements including piezometer tubes, U-tube manometers, and inclined-tube manometers. Examples of calculating pressure using manometers are provided.
