Design Data for Roof and Floor Drainage Outlets

Mana Patarapanich, GG O'Loughlin

Abstract

An extensive programme of full scale hydraulic tests of roof and floor drainage outlets was conducted to obtain their performance characteristics. Relationships between flow rate and depth of ponding for various combinations of outlet bodies and grates or strainers are presented in graphical form. These rating curves are useful in the design of drainage systems for roof and floor areas.
