Sheetal Bansal

The concepts related to Thermodynamics are basics for all topics which fall under the thermal engineering. Hence, understanding thermodynamics and learning all the concepts pertaining to it is highly important for the aspirants of GATE, IES etc. Hence, this course is presented by Sheetal Bansal which will provide you comprehensive information related to thermodynamics. The major topics which are discussed in this course are the Zeroth, First, and Second law of Thermodynamics, Energy interactions, properties of pure substances and ideal gases, and much more. He has also taken up few questions related to thermodynamics which appeared previously in IES and other exams, and has explained the approach to solve them.

In this lesson, Sheetal has given a brief outline on what he will be covering up in this course. He explains why learning the concepts related to thermodynamics important for exams like GATE, IES etc. As he proceeds he explains the benefits of taking up this course for the aspirants. He also briefs about the topics which he will be covering up in this course.

Overview: Understanding of Thermodynamics (GATE, IES, etc.)

In this lesson, Sheetal will introduce the topic Thermodynamics and will explain various important terms used in thermodynamics such as system, surrounding, state of a system , properties of a system etc.

Introduction to Thermodynamics

Through this lesson, one will study zeroth law and concept of temperature, how a thermometer satisfies zeroth law, types of thermometers, definition of thermodynamic work and heat.

Zeroth Law & Heat and Work Interactions

Sheetal Bansal, in this lesson Sheds light on non-flow work for various processes. Then as the lesson proceeds he explains heat flow in various processes.numericals on energy interaction.

Heat and Work Interactions

In this lesson, Sheetal introduces all the aspirants to  the first law of thermodynamics for both cycle and processes. As the lesson moves on one will understand the heat required in various processes. He also briefs about the assumptions used in the first law of thermodynamics. Finally he solves some problems pertaining to the topic.

First Law of Thermodynamics

In this we will study first law for the open system for both steady and unsteady state. Then we will come across the tricks to solve numericals of unsteady state with the help of basic equations . Also we will study various devices like turbine , compressor, nozzle, throttling process

First Law of Thermodynamics for Applied Processes

Here we will solve 3 numerals on unsteady state with the help of basic equations. This lesson will help us understand the proper approach to solve such questions and also helps us to learn simplified method of solving.

Numericals on Steady Flow Energy Equation

In this lesson, Sheetal introduces us to the second law of thermodynamics which is the directional law and give us the direction which a process follows. Here we will introduce the concept of high grade energy and low grade energy, concept of heat engines, refrigerator, heat pump

Second Law of Thermodynamics

Clausius inequality is the most important equation for reversible and irreversible cycles. He explains it relating to thermodynamics temperature scale and efficiency and COP for reversible cycles. Also, he will solve some question on Clausius inequality.

Clausius Inequality

Basics of entropy is an important concept of thermodynamics and here we will be introduced entropy as a property of a system. Entropy change for reversible processes and also what is entropy equation for irreversible process.

Basics of Entropy

Continuation of entropy- here we will discuss entropy change for an irreversible process, for a reservoir, T-S diagram, entropy change for ideal gas, entropy principle

Continuation of Entropy

In this lesson, Sheetal will discuss entropy change for finite bodies, when two different temperature bodies come in contact with each other, maximum work obtained in the process where two different temperature bodies come in contact with each other.

Entropy Change for Various Systems

Here Sheetal will solve some numerical of entropy using basic equations. This lesson would help one to identify important points in the questions, basic approach on how to read such questions and efficient tricks to solve such questions.

Numericals on Entropy

This lesson is in continuation with the entropy lesson and here we will study available energy associated with a heat at a temperature, change in available energy when temperature changes , and degradation of available energy.

Available Energy and Irreversibility

In this lesson, we will come across the concepts related to irreversibility. Here, Sheetal explains  Gaou Stodola theorem. Lastly, he solves some questions on available energy and irreversibility concepts.

Irreversibility and numericals on Available Energy

Through this lesson one will understand the meaning of Pure Substances, various phases diagrams like P-V diagram, P-T diagram , T-S diagram and Mollier diagram , equations of enthalpy, entropy, and specific volume at various points in phase diagrams.

Properties of Pure Substance

Through this lesson, Sheetal makes us understand and learn ideal gas equation, deviations from ideal gas and Vanderwalls equation, conditions for ideal gas, and boundary condition for Vanderwalls equation.

Properties of an Ideal Gas

This is a mathematical lesson and here we will study Clausius Clayperon equation to find latent heat, joule Thomson coefficient for throttling process.

Thermodynamic Relations

From this lesson one can learn how to plot a graph for throttling process, various region in graphs like cooling and heating region, joule Thomson coefficient equation and also for ideal gas, important observation from the graph.

Harshit Aggarwal

One among the major topics which mechanical engineering students learn is Refrigeration. Hence, in this course, Harshit Agarwal concentrates on providing comprehensive information about the fundamentals of refrigeration. One will learn definitions of refrigeration and come across briefly about its fundamentals. One can also attain the comprehensive understanding of vapour compression cycles as the topics pertaining to it are thoroughly explained and sample questions on it are solved. A thorough discussion on the performance of the vapour compression cycle and detailed outline on the volumetric efficiency of a reciprocating compressor is also elucidated. Taking this course makes ones familiar with the classification of refrigerants and much more fascinating topics.
