CHAPTER 9 FLOW THROUGH NON-COPLANAR RECTANGULAR ORIFICE Introduction An Orifice is an opening having closed perimeter, made in the walls or the bottom of a tank or a vessel or a channel containing fluid, through which the fluid may be discharged. Many researchers have attempted flow through multiple slots. However, no literature is available on the non-coplanar rectangular slots which are varying in its location with respect to both horizontal and vertical directions. In this chapter, it is attempted to experimentally find the flow through such varying horizontal & vertical rectangular slots/orifice individually and also together. The main theme of this chapter is to correlate and compare the flow through inclined rectangular weir. Shesha Prakash and Shivapur (Shesha Prakash and Shivapur 2004), analysed flow through the inclined rectangular weir, as the combination of the horizontal and vertical components of the flow. However, they have not provided any experimental validation of the resolution of discharge as horizontal and vertical components. This led to the investigation through non-coplanar rectangular slots/orifices. 9.1 Flow through Non-Coplanar Horizontal Rectangular Orifice: 9.1.1…show more content…
Non-coplanar Rectangular orifice is one in which there are multiple orifices which are not on a single plane but separated with a small vertical obstruction such that they are distributed over different planes. Flow through the single plane orifice has been analysed but the present type of non-coplanar orifice has not been analysed. The head above the horizontal orifice will be a variable for each step of the orifice for which the head-discharge equation has to be derived. In the present case, the cross-sectional area (length and width) of the orifice and the vertical separator is being kept constant, the inclination will be simulated to a rectangular weir of 45o

Abjection is the human reaction (such as terror or horror) to a threatened loss of meaning when confronted by the loss of distinction between the subject and the object: the moment at which the subject (the Cartesian “I”) is confronted
