Pump Analysis Pump Analysis Abstract The purpose of this experiment is to evaluate pump performance based on changes in flow rate. The optimum flow rate for the pump can also be determined. At a fixed speed, pressure difference (pump head) and brake torque in the pump are measured as the flow rate is decreased at predetermined intervals of 2 gpm. The pump’s power input, power output, and efficiency are calculated based on the experimental values. The experiment is carried out successfully, and it is shown that as the pump’s power input is increased, its power output increased to a maximum, then fell. The flow rate at which this drop begins is about 22 gpm. The maximum efficiency for the pump seen during the experiment is 33.9 %, which occurred at 28 gpm. Theory A basic centripetal pump converts fluid velocity into pressure energy by utilizing three components: an inlet duct, an impeller, and a volute. Fluid enters through the inlet duct, and is projected outward as it hits the impeller, which is a series of rotating blades driven by a motor and shaft. The fluid is sent through the pump case located around the impeller, and into the volute (outlet chamber). pump, power, flow, rate, psig, pressure, measured, ft, shaft, input, hp, speed, output, experiment, torque, tn, through, pin, horsepower, fluid, efficiency, converting, pin, water, volute, rpm, pout, lbf/, lbf, increased, impeller Word Count: 690 Acceptance_Essays American_History Anatomy_&_Physiology Animal_Science_&_Zoology Anthropology Architecture Art Astronomy Aviation Biographies Book_Reports Business Computers Creative_Writing Current_Events Economics Education Engineering English Environmental_Science Ethics European_History Film_&_TV Foreign_Languages Geography Government_&_Politics Health_&_Beauty History_Other Human_Sexuality Legal_Issues Marketing Mathematics Medicine Miscellaneous Music Mythology Philosophy Physics Poetry Political_Science Psychology Religion Science Shakespeare Social_Issues Sociology Speech Sports_&_Recreation Supernatural Technology Theater Theses_&_Dissertations
