This report presents a study on the effects of the discharge diameter on the performance of the centrifugal pump. The performance of a centrifugal pump changes when one of the performance characteristics changes. The aim to analyse what happens to the discharge pressure and the stresses experienced at the discharge area when the diameter of the discharge. For most water and other noncorrosive services, stainless steel material satisfies these criteria for the impeller and the casing of the pump. Design constraints and limitation were identified. Boundary conditions were selected. Design of the pump assembly was done on SolidWorks. Results obtained from SolidWorks were interpreted and simulated with ANSYS to determine high stress points and deformation. Graphs were displayed as the results of possible calculations. From the calculated results, it was observed that the discharge pressure, velocity, and the head increases as the discharge diameter decreases. From the simulated results it was observed that as the diameter decreases the maximum stresses experienced as the discharge area also decreases.
