Summary
This study was undertaken to investigate the 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.
The experimental observation of this lab reports has shown that the higher pressure difference the lower the pump discharge (pump flow rate), the longer time it took water to move the lower the flow rate since the mass of water was at constant 10 kg.
The pump efficiency of this laboratory work is relatively low. This could be due to systematic experimental errors during the lab work. The pressure difference of outlet and inlet pressures has major effect on the characteristics of centrifugal pump.
Introduction
The objective of this experiment was to investigate energy transfer in a pump, the centrifugal pumps is common choice for pumping liquid of a low medium viscosity, such as water or oil. It is low in cost, and the rate flow can be arrived quite simply, by restricting the flow rate using a valve. Many centrifugal pumps can even run against a closed valve (no flow) for a short time.
Electrical energy turns the drive shaft. This rotates the impeller within the pump, pressuring the liquid and forcing it to circulate.
In a perfectly efficient system, all the electrical energy, Ee would be converted to shaft energy, Es. This in turn will be converted to fluid energy in the water, Ew. The expressions of
