1 Introduction & Basic ConceptsFluid mechanics is the science of fluids at rest and in motion, and of how they interact with the surfaces they touch. Problems ›

2 Properties of FluidsBefore a flow can be analyzed, the fluid carrying it must be characterized. Problems ›

3 Pressure & Fluid StaticsWhen a fluid is at rest, the only stress it carries is pressure, and pressure variation is governed entirely by weight. Problems ›

4 Fluid KinematicsKinematics describes how fluids move and deform — before any forces enter the picture. Problems ›

5 Mass, Bernoulli & Energy EquationsThree workhorse equations carry most of applied fluid mechanics. Problems ›

6 Momentum Analysis of Flow SystemsWhere the energy equation tracks scalars, the momentum equation tracks vectors — and it is how engineers compute the forces and torques a flow exer… Problems ›

7 Dimensional Analysis & ModelingDimensional analysis is the engineer’s lever for taming complexity: it shrinks a tangle of variables into a handful of dimensionless groups, reveal… Problems ›

8 Flow in PipesPipe flow is the bread and butter of applied fluid mechanics: how much pressure drop, and how much pumping power, does it take to move a fluid thro… Problems ›

9 Differential Analysis of Fluid FlowControl volumes give the big picture; differential analysis gives the detail. Problems ›

10 Approximate Solutions of the Navier–Stokes EquationThe Navier–Stokes equation is almost never solvable as written, so progress comes from knowing which terms to drop and where. Problems ›

11 Flow over Bodies: Drag and LiftWhen a body moves through a fluid — a car, a wing, a golf ball — the flow exerts forces along and across its path: drag and lift. Problems ›

12 Compressible FlowWhen a gas moves fast enough, its density can no longer be treated as constant, and thermodynamics enters the analysis alongside fluid dynamics. Problems ›

13 Open-Channel FlowOpen-channel flow has a free surface and is driven by gravity — rivers, canals, spillways, and partly filled pipes. Problems ›

14 TurbomachineryTurbomachines trade energy between a fluid and a rotating shaft: pumps add it, turbines take it away. Problems ›

15 Introduction to Computational Fluid DynamicsCFD solves the governing equations numerically, opening up flows far too complex for pencil and paper. Problems ›
