Orifice Discharge .
The Orifice Discharge
accessory consists of a cylindrical glass tank which has an orifice
fitted in the base. A traverse assembly is provided which enables a
pitot tube to be positioned anywhere in the jet.
Attached to this
pitot tube is a sharp blade which can be traversed across the jet to
accurately measure the jet diameter and the vena contracta diameter and
so determine the contraction coefficient.
The pitot head and the
total head across the orifice are shown on manometer tubes adjacent to
the tank. In addition to the standard orifice, supply includes four
additional orifices. These are supplied in an attractive storage case. A
label inside the lid gives dimensional details of each orifice.
