Thermodynamics

By Prof. S. R. Kale | IIT Delhi

Learners enrolled: 2111

This course is on basic engineering thermodynamics. The first part, on single component systems, topics are basic concepts and definitions, conservation of mass, 1st and 2nd laws of thermodynamics for closed and open systems, thermodynamic properties of a pure substance and practical applications. The second part covers physical behaviour of a mixture of ideal gases, psychrometry, thermodynamics of reacting systems, combustion, phase and chemical equilibrium, and applications.Lecture notes will be provided and supplemented with assignments that emphasize systematic problem solving.

INTENDED AUDIENCE : Undergraduate students of mechanical engg., and possibly aero- engg. Also any person interested in the basics of energy conversion. Students preparing for GATE, etc.

PREREQUISITES : 12 th standard science (PCM or PCB), and basic knowledge of differential calculus.

INDUSTRY SUPPORT : The course encompasses power generation, I.C.engines, process engineering, refrigeration and air-conditioning, and energy conversion in general, amongst others.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 25 April 2021 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Madras .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
