2. The measurement of Pressure • The Barometer • Manometers • The Bourdon Gauge • Other types of Pressure Gauge Uniform Rectilinear Acceleration Pressure Variation in a variable density fluid and the Standard Atmosphere. helpful 41 1. If the pitot tube is to be used to measure the velocity of a liquid in a pipe, then we must adopt some method to know the static pressure head H. For instance, we may use a pitot tube and a vertical piezometer tube and measure the difference of the liquid levels in the two tubes. Pressure is a normal stress, and hence has dimensions of force per unit area, or {ML-1 T-2}. . . Thought Questions

Why is the electricity produced at the bottom of dams?

When you catch a deep-sea fish, why does its eyes pop-out?

Why do your ears pop on an airplane or up in the mountains?

. Remote sensing is often more convenient than putting a measuring device into a system, such as a person’s artery. • A fluid at rest obeys hydrostatic equilibrium - where its pressure increases with depth to balance its weight : = 0+ • Points at the same depth below the surface are all at the same pressure, regardless of the shape Fluid Mechanics key facts (2/5) Buoyancy and Stability 6.
