Mechanical Engineering

Not really. Rank doesn't really matter when it comes to Indian institutions. Unless you're in an IIT or NIT or NSIT or DTU etc., everything else doesn't really make much of a difference.
Coming to IP university, it may be a Grade A university, but its position with respect to elite institutions in India is questionable. There are some respectable Engineering colleges in IP. But, if you hear from their students, everyone will have some complaint or the other.
What really matters is the kind of job opportunities your field has to offer at the end of your studies. College may play some role, but it is usually your own hard work and effort that will make a difference. Rankings are just a waste of time.

Mechanical engineering is a branch of engineering that applies the principles of engineering, physics and material design for the design, production and operation of machinery.
Mechanical engineers use principles of mechanics, thermodymanics, electricity, materials Science and others to design and analyze manufacturing plants, industrial equipment, machinery, aircraft, robots, weapons and others.
Mechanical engineers create and build mechanical devices. They apply the fundamentals of Science and math to create practical, useful solutions that the rest of us can use.
There is a huge demand for skilled mechanical engineers in India and abroad. The expertise of a mechanical engineer is required in manufacturing industries like automobiles, aviation, etc. In the recent times and due to the advent in technology, the skills of a mechanical engineer is sought in fields such as nano-technology, biomedical engineering, energy conservation and more. According reports, the growth in this industry it is said within the next few years, mechanical engineering will be the highest paid career option.
All the best.
