Fluid Mechanics for Interviews (Mini-Course) with 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.
