To allow for proper drainage in a steam system Or sometimes to maintain a wet return
cavitation formed wen concentric reducer in used. but wat is the use of reducer in the both suction and discharge side of the pump. if we dost use (conc & ecc) reducer in the both sides.. there is not effect on pump
All the planets in the solar system have very low eccentric orbits.
Concentric and eccentric movements.

formula to find volume of an eccentric reducer
The pump discharge reducer doesn't matter if it's concentric or eccentric. It's the pump SUCTION that needs to be an eccentric reducer that is always flat on top (F.O.T.) The eccentric reducer on the pump suction reduces pump cavatation (pump catching air).
An eccentric reducer is mostly used to force air in a direction, normally towards a pump or airvalve so that it does not get trapped inside the pipework.

Concentric reducers are a symmetrical, conical shaped device that enlarges or reduces a pipes diameter equally about the centerline. An Eccentric reducer is not Symmetrical about the centerline. For example, envision the flow through a gravity based pipe... picture it in terms of an elevation section view... the eccentric reducer maintains the flowline (a straight continuous line along the bottom) while the pipe size decreases from the top down.
if we use concentric reducer at suction of pipe ,due to high turbulence flow of fluid ,some vapour pressure generate which generate bad effects on impeller of pump ,which decrease pump efficiency , so to avoid this problem the eccentric reducer's use in pump suction
Doesn't matter
Very depend on the application, concentric pipe had lower pressure drop and better flow distribution. However, in many case, eccentric pipe reducer is installed on propose to allow liquid drainage from reducing in horizontal pipe.

It is so that the inside bottom of the line can drain completely if required and no fluid or condensate will remain trapped. In other words the eccentric reducer keeps the bottom of the line straight.
