Objectives
This experiment is conducted to first calibratethe orifice meter, turbine meter, rotameter and ultrasonic flowmeter (over a range of flow rates) in order to obtain accurate data to be used for the rest of the experiment. Through this experiment and subsequent calculations, the discharge pressure can be expressed as a function of flow rate and rotational speed for both the gear pump and the centrifugal pump. Finally, the efficiency of the gear pump and the centrifugal pump can be related to both the rotational speed and the flow rate to see how one affects the other.
Introduction
LACIMEHC CHEMICAL Inc. is seeking guidance to find out what kind of flow meter they should use, as well as which kind of pump will minimize their costs. This task can be accomplished by changing flow rates through both a centrifugal pump and gear pump by varying the motor speed and discharge pressure. For each trial, readings from the rotameter, orifice meter, turbine meter, and ultrasonic flow meter can be recorded. The readings for flow rate can then be plotted and compared. The results can be discussed to determine the best combination of pump and meter by analyzing the efficiencies for the two pumps. Depending on which meter is the most accurate and efficient, will determine the best option.
