"The Coil Pump" by G.H. Mortimer and R. Annable


On these pages I have scanned an article from Volume 22, No. 1 (1984) of the Journal of Hydraulic Research by G.H. Mortimer and R. Annable. The abstract is as follows:
An old idea for a simple pump has been developed and from laboratory investigations a theory has been produced which satisfactorily predicts the pump's behavior. A low cost stream powered version of the pump was built and successfully tested in a local stream.
