Abstract: Frictions are of two type i.e. internal friction and external friction, internal friction as well as external friction of water mainly depends upon Physico-chemical characteristic of water (liquids). It is due to turbidity, hardness, conductivity, temperature and dissolved oxygen of water. External friction can be reduced by different techniques such as by internal coating of pipes in which liquid flow and by increasing or decreasing diameter of pipes. Still it has some internal and external frictional losses. Those frictional losses can also be reduced by the addition quantitative and qualitative amount of surfactant and other chemicals in the water samples. Co-efficient of Friction ‘F’ of pipe play very important role in fluid mechanics. Co-efficient of Friction initially decreases by the addition of sodium hydroxide and surfactant at diameter two but at diameter one F value initially decreases then increases.
