  • Patent number: 7740483
    Abstract: A portable apparatus and method for demonstrating different characteristics of different fluids that includes different fluid sumps or chambers for receiving samples of the different fluids. A test shaft having different portions that are immersed in the different fluid samples in the chambers is driven by an electric drive motor at a substantially constant speed while substantially the same amount of friction or force is applied to the different portions of the test shaft at different times to increase the resistance presented to the drive motor. The additional amount of current drawn or power absorbed by the motor or strain induced in the motor drive shaft during the application of such friction or force to the different portions of the test shaft is monitored and compared to provide a comparison of the friction or power loss characteristics of the different fluid samples.
