Momentum Transfer in Fluids

By Prof. Sunando DasGupta, Prof. Somenath Ganguly | IIT Kharagpur

Learners enrolled: 71

ABOUT THE COURSE:
The objective of this course is to introduce the students to the fundamental concepts of momentum transfer operation as it applies to fluids. The course will start at the basics and move towards applications normally encountered in Chemical Engineering applications. The course will be built around the concepts of flow physics including hydrostatic forces, conservation of mass and momentum using differential and integral approaches, concept of boundary layers, skin friction as well as measuring devices. More importantly, the course will treat the fluid flow process as a unit operation similar to heat, mass, and charge transfer operation, which is easily understandable by the participants from different backgrounds. The inviscid flow and the use of complex potential and streamlines will be demonstrated, drawing analogy with electrical field lines, so that the participants can relate the concepts with other physical processes. Turbulence and turbulent flows will be introduced.

INTENDED AUDIENCE: 2nd year UG students of Chemical Engineering / Petroleum Engineering / Environmental Engineering / Biomedical Engineering / Energy Engineering / Pharmacy / Biotechnology / Materials Engineering / Nuclear Engineering / Mechanical Engineering / Civil Engineering / Aeronautical Engineering

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: May 3, 2025 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

Please note that assignments encompass all types (including quizzes, programming tasks, and essay submissions) available in the specific week.

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 Kharagpur .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.
