3. Purpose of Engineering /Education/Research
Devaprakasam D, Email: devaprakasam.d@vit.ac.in, Ph: +91 9786553933
There are two important purposes and driving force
behind the Engineering/Education/Research:
1. Minimum consumption of Energy and Materials
without sacrificing the efficiency and functionality.
2. Maximum conversion of Energy from one form to the
other, to identify or design highly efficient process or
system.
