Abstract This laboratory projected explored the performance of two pumps and three flow meters, in order to make recommendations on investment and operation of these common fluid processing necessities. Nearly every chemical production facility around the world will use these specialized, engineered devices in order to process and manufacture chemicals. Experiments were conducted using water as the motive fluid-, and the results obtained can be extrapolated to other fluids as well. Various flow devices, including a rotameter, a differential pressure orifice flow meter, and a turbine flow meter, were all calibrated accurately in order to ensure reliable data. At the conclusion of the project, a gear pump and a centrifugal pump were characterized in terms of performance and efficiency. Table of Contents Introduction This laboratory projected explored the performance of two pumps and three flow meters, in order to make recommendations on investment and operation of these common fluid processing necessities. Nearly every chemical production facility around the world will use these specialized, engineered devices in order to process and manufacture chemicals. Companies must spend significant funds on pumps, and the investments they make must work properly, provide reliable and safe performance, and fit the service requirements of the process stream. Flow meters are extremely valuable in process control and operation, so it is desirable to have the most accurate and most dependable device possible. Experiments were conducted using water as the motive fluid, and the results obtained can be extrapolated to other fluids as well. In order to collect data on the pumps, experiments were performed to calibrate the various flow devices, including a rotameter, a differential pressure orifice flow meter, and a turbine flow meter. After calibration, the pumps could be further analyzed and characterized in terms of discharge pressure, capacity, and efficiency at various speeds and process conditions. Theory In order to move liquids, pumps are often called upon to increase the fluid’s mechanical energy. One manner in which the increase in energy is discussed is through the concept of fluid head. This is a convention describing the energy developed by the pump in terms of the height of fluid it could support if only straight vertical piping were connected to the pump’s discharge. A specialized mechanical energy
