MRW-002 IGNOU Guess Paper 2026-27

MRW-002 Heat Transfer Guess Paper (Digital PDF) for Term-End Exam (TEE)

This structured guess paper aligns with IGNOU’s official MRW-002 syllabus, emphasizing solved previous year questions and high-scoring topics from June/December sessions. Designed for 3-hour exam efficiency, it includes chapter-wise weightage, conceptual shortcuts, and application-based questions to ensure strategic preparation.

Key Syllabus Blocks & Focus Areas

• Block-1: Introduction to Heat Transfer
  • Steady-state vs. transient conduction, modes of heat transfer, and dimensional analysis in heat transfer.
  • Previous TEE emphasis on Fourier’s law and thermal conductivity of materials (e.g., metals vs. insulators).
• Block-2: Conduction
  • One-dimensional steady-state conduction with boundary conditions (e.g., convection, radiation).
  • High-weightage on Fourier’s equation solutions for planar, cylindrical, and spherical geometries.
• Block-3: Convection
  • Newton’s law of cooling, Nusselt number, and forced/convection correlations (e.g., Dittus-Boelter equation).
  • Frequent TEE questions on heat transfer coefficients for internal/external flows.
• Block-4: Radiation
  • Stefan-Boltzmann law, view factors, and blackbody/graybody radiation.
  • Application-heavy questions on solar collectors and greenhouse effect calculations.
• Block-5: Heat Transfer Applications
  • Transient conduction (lumped system analysis), heat exchangers (LMTD/NTU methods), and phase change problems.
  • Previous papers often include real-world scenarios (e.g., cooling systems in renewable energy devices).

Exam Time Management Tips

• Allocate 40-45 minutes per block (e.g., 15 mins for conduction math, 20 mins for convection theory).
• Prioritize numerical problems in Blocks 2 and 3 (highest TEE marks).
• Spend 10-12 minutes on Block-5 applications to leverage application-based questions.

Subject-Specific FAQs

• Q: Which topics are most frequently asked in TEE?

  Fourier’s law (Block-1), convection correlations (Block-3), and radiative heat transfer (Block-4) consistently appear in 60-70% of questions. Focus on derivations and real-world examples.

• Q: How to solve transient conduction problems efficiently?

  Use the lumped capacitance method for Biot number < 0.1 and Heisler charts for Biot > 0.1. Practice dimensionless analysis (e.g., Fourier number) to save time.
