PROJECT AIM
Our main aim to study Acoustic and Mechanical properties
of PVC Pipe.
Targeted Remedies
By using high density filler (using Barium Sulphate).
By reducing coefficient of friction between inside wall of
pipe and flowing water.

CONCLUSION
After complete evaluation and analysis, we conclude that formulation 3 is
providing optimum output for our target i.e minimum sound generation and
mechanical properties on higher side.
It was overall an effective and informative experience for us to work on this
project in industry. Starting from raw material dealing to practical working
on machines were noteworthy. This project supported our technical and
theoretical knowledge during practical approach.
