Webfluid flow through open containers with holes or barriers. The flow of a fluid jet out of a sharp-edged orifice rarely has the same area as the orifice due to a fluid flow phenomenon known as the vena contracta. The area of a fluid jet out of an orifice is related to the actual area of the orifice by a value known as the coefficient of ... Webrange from 5·6 to 5·65, i.e. the actual flow through a sharp edged orifice is approximately 656 of the theoretical value. The value of the Coefficient of Discharge may be determined by measuring the quantity of water discharged over a period of time whilst the head is maintained at a constant level.

This will ensure a constant head and produce a steady flow through the orifice. If necessary, adjust the frame so that the row of needles is parallel with the jet, but is located 1 or 2 mm behind it. This will avoid disturbing the jet, but will minimize errors due to parallax.
