The New Hydraulic Institute Pump Intake Design Standard
MetadataShow full item record
A balanced committee of users, designers, researchers, and pump manufacturers has produced a revised Hydraulic Institute Pump Intake Design Standard that is considerably different from the existing standard and more comprehensive. An overview of the new features of the revised standard is provided. The discussion focuses indepth on selected portions of the new document, including rectangular intakes, trench type intakes, and the concept and use of “design bell diameter.” The basis for the minimum submergence rule, hydraulic modelling requirements, scope, and acceptance criteria are covered.
