Flow through orifices
WebMay 6, 1999 · Liquid flow. For liquids where the pressure at the orifice is known in units of length (head): Q = khD2√h. where Q = the mass flow rate in units of mass/time, D = orifice diameter in units of ... WebMany variables affect the flow through orifices. One variable is the hole diameter. Flow varies directly with the area of the hole or is a function of the hole diameter squared. Other variables affecting the flow through a hole of a fixed diameter include the shape of the entrance and the depth of the hole relative to its diameter. Some of ...
