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.

COST ANALYSIS

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.
