This paper describes the development and assessment of a pump flow take-home experiment that was implemented in an introductory junior-level fluid mechanics course in Fall 2005. The takehome experiment, along with appropriate instructions, is assigned as homework. Students borrow the equipment from the department's equipment room, and perform the experiment either at home or in the student lounge or student shop work area. The experimental apparatus consists of a bucket, tape measure, submersible aquarium pump, tubing, measuring cup, and extension cord. Students connect the tube to the pump outlet, submerge the pump in water, and measure the volume flow rate produced at various outflow elevations. They record and plot volume flow rate as a function of outlet elevation, and compare with the manufacturer's pump performance curve (head versus volume flow rate). The homework assignment includes an online pre-test and posttest to assess the change in students' understanding of the principles of pump performance. The results of the assessment support a significant learning gain following the completion of the takehome experiment. These results and analysis of student perception data collected via an online survey embedded in the homework assignment are discussed.
