Fluid Mechanics for Interviews (Mini-Course)
Chirag Jain
Fluid Mechanics is another core subject tested in Chemical Engineering interviews. From the fundamentals of flow equations to real-world pump operation, recruiters frequently test both your conceptual clarity and your ability to apply it to equipment design and troubleshooting.
This 4-hour mini-course is tailored to give you interview-ready confidence in Fluid Mechanics.
🌟 What’s Included
🎥 2 × 2-Hour Recorded Lectures – covering fluid mechanics in a structured, application-focused manner.
📑 50-Page Notes PDF – crisp, well-organised notes to revise before interviews.
📌 Topics Covered (with Interview Focus)
- Why Fluids Flow? – pressure gradients, gravity, and driving forces.
- Continuity Equation (Mass Conservation) – A₁V₁ = A₂V₂, basis for pipe/pump sizing.
- Bernoulli’s Equation (Energy Conservation) – head, pressure, velocity; pump head calculations.
- Pressure Concepts – static, dynamic, total pressure.
- Head Losses in Pipes – Darcy–Weisbach equation, major vs. minor losses, impact on pumps.
- Pumps Overview – why we need pumps, classification (positive displacement vs. centrifugal).
- Centrifugal Pumps (Most Common in Industry) – construction, working, radial/axial/mixed flow.
- Priming of Centrifugal Pump – necessity and process.
- Cavitation – causes, effects, and prevention in pumps.
- Net Positive Suction Head (NPSH) – NPSHa vs. NPSHr, calculation with example.
- Pump Curves & Affinity Laws – impact of speed/impeller size on performance.
- Pump Efficiency & BEP – efficiency curve, best operating point.
💡 Why Take This Course?
- Focused on the most-asked interview questions in fluid mechanics.
- Includes both theoretical fundamentals and practical pump insights.
- Access to recordings + notes that you can revisit anytime.
👉 By the end of this course, you’ll be able to answer confidently in interviews on fluid flow and pumps, whether the question is theory-based (continuity, Bernoulli, NPSH) or application-based (pump selection, cavitation, efficiency).
