BPVI-012 IGNOU Guess Paper 2026-27

BPVI-012 Guess Paper: Diary Equipment and Utilities Term-End Exam (TEE) Preparation

This structured guess paper aligns with the official IGNOU curriculum for BPVI-012, focusing on high-yield topics from previous year papers (2018–2023) and exam weightage distribution. It prioritizes Block-1 (Dairy Equipment and Their Maintenance), Block-3 (Steam Generation and Boilers), and Block-4 (Electrical Engineering and Safety Devices), with a 3-hour exam time management strategy.

Chapter-wise Question Weightage & Focus Areas

• Block-1: Dairy Equipment and Their Maintenance
  • 20–25% weightage: Types of milking machines (vacuum-based, pneumatic), their working principles, and routine maintenance checks (e.g., pulsator timing, valve cleaning).
  • 15–20% weightage: Lubrication schedules for dairy equipment (e.g., bearings, seals) and troubleshooting common issues (e.g., air leaks in milking systems).
• Block-3: Steam Generation and Boilers
  • 25–30% weightage: Boiler types (fire-tube vs. water-tube), efficiency calculations, and safety devices (pressure gauges, safety valves).
  • 15–20% weightage: Water treatment for boilers (softening, deaeration) and scale formation prevention.
• Block-4: Electrical Engineering and Safety Devices
  • 20–25% weightage: Motor starters (direct-on-line, star-delta), wiring diagrams for dairy equipment, and fault diagnosis (e.g., short circuits, overloads).
  • 10–15% weightage: Safety standards (IS codes), earthing systems, and emergency shutdown protocols.

3-Hour Exam Time Management Tips

• Allocate 45 minutes for Block-1 (short-answer questions on equipment types and maintenance).
• Dedicate 60 minutes to Block-3 (long-answer questions on boilers and steam systems, including calculations).
• Reserve 30 minutes for Block-4 (diagrammatic questions on electrical circuits and safety devices).
• Spend 15 minutes reviewing all answers, ensuring units are included in calculations and diagrams are labeled clearly.

Sample High-Scoring Questions (Based on Previous Papers)

• Block-1: Explain the working principle of a vacuum-based milking machine with a labeled diagram. Describe preventive maintenance steps for the pulsator mechanism. (20 marks)
• Block-3: Calculate the efficiency of a fire-tube boiler given the following data: Fuel input = 5000 kcal/kg, steam output = 3500 kcal/kg, and losses = 500 kcal/kg. (15 marks)
• Block-4: Draw the wiring diagram for a 3-phase motor starter with overload protection. Explain the role of a thermal relay in this setup. (15 marks)

Subject-Specific FAQs

• Q: Are numerical problems common in BPVI-012 exams?

  A: Yes. Blocks 3 (boiler efficiency) and 4 (motor power calculations) frequently include numerical questions. Practice unit conversions (e.g., kcal to kWh) and efficiency formulas (η = Work Output / Work Input).

• Q: How should I approach diagram-based questions?
