A small pump (about 10mm on a side) with a rotating helical wire was developed. Hydrodynamic forces generated by the small pump were measured by varying the rotational speed of the helical wire and by varying the fluid viscosity. The measured hydrodynamic forces agree well with those predicted by using the resitive theory based on the hydrodynamics of flow at a low Reynolds number. The measured hydrodynamic forces generated by the pump were proportional to the rotational speed of the helical wire. This suggests that the small pump can be used to control hydrodynamic forces with high accuracy. Furthermore, the hydrodynamic force generated by the pump was also proportional to the fluid viscosity. This suggests that this pump is also a small viscometer.
