💥Engineering Thermodynamics GTU IMP 2025🔥 | BE Mechanical Sem-3💯 | Top IMP Questions & PDF📚✅ #gtuimp

Summary

The video presents a chapter-wise list of important Engineering Thermodynamics questions for GTU B.E. Mechanical Semester 3 students, particularly those preparing for an exam. The presenter says the material is free and intended to help students prioritize revision; it is not a guarantee of passing.

Exam-Writing Advice

• Draw and label relevant diagrams when a question calls for one.
• Follow the expected paper format, and write answers neatly, clearly, and point by point.
• Attempt questions in sequence where possible. If you skip a question, continue in order rather than jumping around unnecessarily.
• Revise definitions and practise the selected questions and cycle diagrams.
• The presenter suggests that preparing a focused set of roughly 5–10 questions, along with clear presentation, may help students earn marks. The video mentions 23 out of 70 as the passing threshold, but students should check the applicable exam rules.

Topics Highlighted

Introduction to Thermodynamics

• Definitions of system, surroundings, and boundary
• Types of thermodynamic systems; explain any one type
• Thermodynamic properties, including intensive and extensive properties
• Equilibrium and processes
• Path and point functions
• Open, closed, and isolated systems
• Open and closed cycles, and comparisons between related concepts

Thermodynamic Laws and Entropy

• Conservation of mass and conservation of energy
• The first law of thermodynamics
• The second law, especially the Kelvin–Planck statement
• PMM2 (perpetual motion machine of the second kind), as identified in the subtitles
• Entropy: its definition, properties, and characteristics

Heat Engines, Refrigeration, and Cycles

• Definitions and working principles of heat engines and refrigeration
• Thermodynamic cycles, including the Rankine cycle, which the presenter emphasizes as especially important
• Cycle diagrams, including T–s and h–s diagrams, as transcribed in the subtitles
• Advantages and disadvantages of the Rankine cycle
• Other named cycles are mentioned, but some names in the auto-generated subtitles are unclear. Students should verify them against the PDF or course syllabus.
