characteristics of a Centrifugal pump. The Centrifugal pump is largely used in petrochemical industries to move liquids around the plants and refineries. Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work in terms of pump discharge pressure‚ pump efficiency‚ and power demand at various pump speeds of verses pump discharge.

ECON1101 Essay: Petrol subsidies in Nigeria Nigeria‚ an oil-abundant nation‚ produces two million of barrels of crude oil a day‚ though despite this‚ it relies solely on importation to sustain its refined-fuel needs. This is because its four refineries fail to function effectively and continue to operate beneath capacity. Governmental mismanagement and political corruption are some of the reasons why Nigeria’s refineries remain in this state. The Nigerian government therefore implemented subsidies

Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping system.[1][2] Centrifugal pumps are used for large discharge through smaller
