Power Consumption of a Terg-O-Tometer

Abstract

One of the most convenient means of running small-scale tests on washing or rinsing equipment is through the use of a commercially available test fixture called a Terg-O- Tometer. Unfortunately, however, this test fixture does not provide for measurement of the net power transmitted to the liquid bath. Since information on power input is vital to the proper evaluation of a cleaning process, a means was devised to directly measure this power input. The power input, characterized by the power number, was obtained for various Rey nolds number values, where the Reynolds number was used as a measure of the speed and stroke angle variations. Information on power input versus water level variation and varying cloth load quantities was also obtained. In general, net power input in creases with increasing water bath volume and increasing cloth-to-water ratio.
