IES Mains Exam Analysis 2019:- UPSC will conduct IES Mains examination for the candidates who have cleared the preliminary examination on 30th June 2019. We will update you with detailed Exam Analysis of IES Mains Exam 2019 in this post.

• Mains examination for IES 2019 is the upcoming stage in order to clear UPSC IES exam.
• In this post, we will update you with shift-wise exam analysis for IES Mains 2019
• Exam Analysis will help you understand the nature of the UPSC IES Mains Exam. For better understanding, we have mentioned a detailed analysis of UPSC IES 2018 Mains examination.

### IES Mains Exam Analysis 2019

The UPSC IES 2019 Mains (stage 2) examination will have 2 papers. Both the papers will have questions from the selected Engineering discipline (Civil Engineering, Mechanical Engineering, and  Electrical / Electronics & Telecommunication Engineering).

To be Updated

### IES Mains Exam Analysis 2018 (Previous Year Student’s  Analysis)

Here we have brought for you, Previous year’s Student’s Analysis for Civil, Mechanical, Electrical, Electronics & communication Mains examination conducted in the year 2018.

This will give you an idea of the examination and it will certainly act as an important guide in your chase of becoming Engineering in the Indian Govt. sector employer Indian Engineering Services.

#### Mechanical Engineering ESE (Paper I) Analysis

Section A – Compulsory Question Q 1. (12*5=60 marks)

(a) Refrigeration and Air Conditioning Problem – Calculation of COP – Level (Moderate) – Reference: CP Arora

(b) Internal Combustion Engines Theory – Knocking Phenomenon in SI and CI Engines – Level (Easy) – Reference: ML Mathur & R P Sharma

(c) Fluid Mechanics Problem – Boundary Layer Theory – Level (Difficult) – Reference: Introduction to Fluid Mechanics: Fox 5th ed (Ex-9.1) – (Boundary Layer in Channel Flow)

(d) Heat Transfer Problem – Radiation – Level (Moderate) – Reference: Frank P Incropera- Fundamentals of Heat Transfer – Chapter 12 – Radiation

(e) Refrigeration and Air Conditioning Theory – Properties of Refrigerants – Level (Easy) – Reference: CP Arora

Section B – Compulsory Question Q 5. (12*5=60 marks)

(a) Engineering Thermodynamics Problem – Entropy Change Calculation – Level (Moderate) – Reference: Engineering Thermodynamics – Yunus Cengel – Chapter 7 Entropy (Exercise Question 7–66)

(b) Renewable Sources of Energy Problem – Harnessing of Wind Energy and Calculation- Level ( Difficult) – Reference: Energy Conversion System – Rakosh Das Begamudre – Chapter 5 – Wind Energy Conversion ( Ex 5.4 )

(c) Turbomachinery Theory – Steam Turbines Blades – Level (Moderate) – Reference: Power Plant Engineering P K Nag – Chapter 7 – Steam Turbines

(d) Renewable Sources of Energy (Theory and Derivation) – Flat Plate Solar Collector – Level (Difficult) – Reference: Power Plant Engineering P K Nag for theory ( 14.5.1 Solar Thermal Conversion), Refrigeration and Air Conditioning C P Arora for derivation ( 17.11 Flat Plate Solar Collector)

(e) Internal Combustion Engines Theory – Rubbing Losses, Pumping Losses, Frictional Losses – Level ( Easy) – Reference: ML Mathur & R P Sharma

#### Compulsory Questions Weight age Analysis

Fluid Mechanics – 12 marks “ Difficult”

Thermodynamics – 12 marks “ Moderate”

Heat Transfer – 12 marks “ Moderate”

Internal Combustion Engines – 12+12=24 marks “Easy”

Refrigeration and Air Conditioning – 12+12=24 marks “Moderate+Easy”

Turbomachinery – 12 marks “Moderate”

Power Plant Engineering – 0 marks

Renewable Sources of Energy – 12+12=24 marks ( New Syllabus) “Difficult”

Theory questions were asked from standard textbooks within the prescribed syllabus. Numerical were of moderate to difficult level, some were directly taken from examples and unsolved problems of foreign authors (Fox, Cengel, Incropera), derivations were asked specifically for the new syllabus (Renewable Sources of Energy) P K Nag and C P Arora comes handy in this scenario.

Choose the remaining questions (three in number) as per your aptitude and competence to maximize the score. I will do the analysis for Mechanical Engineering ESE Paper II 2017 in the upcoming days.
