Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Ideal Liquid, Stream-lined Flow, and Turbulent Flow, 2. Viscosity, Velocity Gradient, and Newton's Law of Viscosity, 3. Stokes' Law, Terminal Velocity, and Applications.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 41 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Flow of Liquids after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Ideal liquid has zero compressibility and zero viscosity.
  • Real liquids are only approximately incompressible.
  • Water changes volume by only 0.000048 under one atmospheric pressure.
  • Streamlined flow has fixed paths and constant velocity at a point.
  • Turbulent flow has mixed, irregular motion.
  • Two streamlines cannot intersect.
  • Critical velocity separates streamlined and turbulent flow.
  • Formula: vc = kη/(ρD).
  • For water in a narrow tube, Reynold's number is about 2000.

Common Mistakes to Avoid

Bernoulli’s theorem works for any moving fluid in any situation.

Critical velocity is the speed above which flow becomes streamlined.

Reynolds number ranges are only below 2000, above 2000, and above 3000.
