sweepage (countable かつ uncountable, 複数形 sweepages)

1. (Britain, dialect) The crop of hay obtained from a meadow.
   • 2011, Robert Hunter, The Preservation of Open Spaces, and of Footpaths, and Other Rights of Way, →ISBN, page 61:

     This right is defined by Lord Coke to extend to the enjoyment of the corn, grass, underwood, sweepage (i.e. everything which falls to the sweep of the scythe), and the like, but not to houses, timber, trees, or mines, .or inany way to the land itself

2. The process by which gases passing beneath the electrodes of an electrostatic precipitator pick up dust from the hoppers, removing it from the precipitator exit.
   • 1978, Sabert Oglesby, ‎Grady B. Nichols, Electrostatic Precipitation (volume 21, page 260)

     One consequence of poor gas flow is hopper sweepage. High gas flow near the bottom of the precipitator and improper baffling can cause gas flow into the hopper area.

   • 1994, Howard D. Hesketh, Air and Waste Management: A Laboratory and Field Handbook, →ISBN:

     Another qualitative test which should be performed during the geometric model study is the injection of neutral buoyancy smoke into the roof and hopper regions of the collection chamber, particularly near the outlet, to check that significant amounts of gas are not exiting the precipitator without passing through the collecting plates (' ' sneakage' ' ) and that there are not strong flows in the hopper regions (hopper sweepage) which could cause excessive reentrainment.

   • 2010, Mario L. Occelli, Advances in Fluid Catalytic Cracking, →ISBN, page 366:

     Nonuniform gas flow or maldistribution will result in poor collection, excessive reentrainment, or hopper sweepage.

   • 2014, Arthur C. Stern, Air Pollution V4: Engineering control of Air Pollution, →ISBN, page 254:

     However, observation of the hopper area and the outlet field can usually detect the presence of heavy dust reentrainment either by hopper sweepage or by scouring of the plates.

3. Detritus that is swept up with a broom or similar implement.
   • 1891, United States Bureau of Foreign Commerce, Special Consular Reports, page 225:

     The drainage, or flow of suds into road ditches or borders, or the drainage of water upon the road itself, as well as any pollution of the same by rubbish, stones, and sweepage from houses or stables, etc., is prohibited.

   • 2005, K.R. Gupta, Environment : Problems And Policies, →ISBN, page 38:

     Those who carried it were twelve or thirteen fishermen, with a little number of others of the same cloth, without credit, without arms, without courage, without experience, the offscouring and sweepage of the world, weakness and imbecility itself, who instead of smiting and slaying were whipped and stoned at every turn; instead of attacking, did not so much as make resistance to them that ill handled them, living in extreme humility and innocence.

4. The circuit of an oscilloscope used to track the time dimension.
   • 1938, Japanese Journal of Engineering. Abstracts - Volumes 16-20, page 63:

     The transient visualizer used in the past were mostly of types in which the voltage for the time sweepage is generated by a relaxation oscillation circuit made up of a hot-cathode discharge tube, say, a thyratron, and a condenser, and the control voltage for the generation of the transient to be observed is also generated by the same circuit.

   • 1939, Electrotechnical Journal: ETJ. - Volumes 3-4, page 228:

     Between the rectangular impulse circuit and the time sweepage circuit of the oscillograph, the synchronizing circuit formed by the grid circuit of the tube Bi is inserted.

   • 2008, ‎Pramod Bansi Mathur, A Hand Book of Clinical Endodontics, →ISBN, page 21:

6. The movement of matter by a current.
   • 2000, SPE Reservoir Evaluation and Engineering, page 463:

     In reservoirs characterized by the presence of well-connected high-permeability streaks, early breakthrough and subsequent water buildup occur due to sweepage along high-permeability channels.

   • 2001, Bryan G. Crowther, Handbook of Rubber Bonding, →ISBN, page 75:

     Common causes of CM failure include poor metal preparation, i.e., the presence of contamination on the metal before applicaton of adhesive, insufficient dry film thickness of primer, failure to properly agitate the adhasive to achieve a uniform dispersion prior to application, environmental attack (salt, water) on the primer/metal interface, dry spray of primar on to the metal (which does not allow the primer to adequately wet out the metal surface), or sweepage (when the flow of rubber strips some または all of the adhesive または primer film from the metal surface) of the primer and adhesive off the metal during injection or transfer moulding.

   • 2004, Yuanhui Zhang, Indoor Air Quality Engineering, →ISBN, page 388:
