(SEM IV) THEORY EXAMINATION 2024-25 ENERGY SCIENCE & ENGINEERING

This document contains the complete B.Tech (Semester IV) Theory Examination 2024–25 question paper for Energy Science & Engineering (BOE404). The paper spans two pages, carries 70 marks, and evaluates a student's understanding of renewable and non-renewable energy resources, solar–wind–hydro power systems, nuclear energy, thermodynamic cycles, green buildings, energy conversion technologies, and global energy challenges.
 

Section A – Short Conceptual Questions (14 Marks)

Section A includes seven 2-mark questions focusing on essential fundamentals of energy science (Page 1). Questions test understanding of:

Photo and thermal phenomena in solid-state materials

Difference between gas power cycle and steam power cycle

Nuclear fission vs nuclear fusion

Key features of solar photovoltaic devices

Concept of Ocean Thermal Energy Conversion (OTEC)

Definition of nuclear radiation

Meaning of Green Building and its sustainability aspects

These are foundational concepts from solar, nuclear, and thermal sciences.

Section B – Analytical & Medium-Length Questions (21 Marks)

Students attempt any three out of five. These questions require explanation, diagrams, and applied understanding (Page 1):

Electromagnetic Energy

Methods of storage, conversion, and radiation of electromagnetic energy.

Nuclear Fusion

Process of nuclear fusion and how it naturally occurs in the Sun.

Solar Radiation

Fundamentals of solar radiation and various measurement techniques.

Wind Turbine Design

Construction and dynamics of wind turbines, supported by neat diagrams.

Global Energy Scenario

Overview of world energy trends with emphasis on renewable energy sources.

These questions target applied energy concepts and renewable systems.

Section C – Long, High-Level Questions (35 Marks)

Section C consists of five comprehensive questions, each with two alternatives, requiring detailed explanations, diagrams, or technical reasoning (Pages 1–2).
