The purpose of this investigation is to determine what percentage, if any, of a freestream velocity head is recovered by the flow through a slot. In this experiment, fluid is drawn through a slot placed perpendicular to a passing flow. This project addresses orifice coefficients, a classic subject, which has been thoroughly investigated. However, unlike most of the previous experiments measuring orifice or resistance coefficients, the flow approaching the orifice, or slot in this case, is not symmetrical. Mainstream flow rate and orifice flows are explored systematically over a fairly wide range. The primary motivation is to gain a better understanding of the fluid dynamics associated with small orifices in the presence of a passing flow.
