AIM AND OBJECTIVES

As we know that when water from height are falling down in the pipe, it create sound which may disturb human beings .

Our main aim to reduce the sound which occurs during water flowing in the pipe.

Targeted remedies

By increasing the density of fillers.

By reducing coefficient of friction between inside wall of pipe and flowing water.
