Flow through slot(s) is of practical interest as a first step in the analysis of flow through similar passages in gas turbine combustor chamber walls and the like. Attention is presently given to the results of an experimental investigation of flow entering a channel that is blocked at its back end, and exits from a lower channel that is blocked at its front end; the two channels are. The implications of treating flow through a side slot as through a small orifice, as reported in the literature, are also studied. For different combinations of slot openings and sill heights, data for a set of 110 runs have been obtained.
Flow through gate openings has been the subject of study by many investigators. Gates are often located on raised crests, as in the case of spillways. In such a situation, the flow is expected to behave similarly to flow through rectangular slots. As flow through a rectangular slot is a particular case of flow through a large orifice, any understanding of it will help in its generalization. Furthermore, because the flow through a slot is intermediate to that of a sluice gate and a rectangular sharp-crested weir, it can be used as a basis of unification. In this study, a discharge equation for flow through rectangular slots has been obtained. In special cases, this equation converts to the discharge equations of a sluice gate and a rectangular sharp-crested weir.

This article provides calculation methods for correlating design, flow rate and pressure loss as a fluid passes through a nozzle or orifice. Nozzles and orifices are often used to deliberately reduce pressure, restrict flow or to measure flow rate. FLOW THROUGH NON - COPLANAR RECTANGULAR HORIZONTAL SLOTS. A slot is a weir regardless of whether it fits into any standard model of a weir. The important characteristic of a weir that it is free surface flow and at some point the flow is at minimum energy (at transition from sub critical to super critical critical depth if you like). You can calculate the flow through a weir/slot from this principle.
