, 2013 In this Master Thesis jet pumps have been reviewed. Jet pumps are considered as a higher volume artificial lift method and operates by passing a high-pressure fluid jet through a venturi system. Cunningham's equations on jet pumps have been chosen to present the jet pump fluid mechanics.Factors impacting the jet pump performance have been investigated ...
