Identify the missing data.(a) Jetting hole(b) Header(c) Riser(d) Swing

1.	Identify the missing data.(a) Jetting hole(b) Header(c) Riser(d) Swinger armI got this question during an interview.The query is from Deep Excavations in section Deep Excavations, Pile Foundations and Caisson of Construction & Building Materials
Answer» CORRECT choice is (b) Header Easiest explanation: A Header is a PIPE to which all the swinger ARMS of the different well points are attached. The header, in turn, is connected to a pumping UNIT. The header is laid on the ground and its diameter varies from 150 mm to 250 mm.
