Orifices are widely used as flowmeters in industries, automobiles and other mechanical equipment’s. Significant research has been done in this field but is still in potential area of research. This paper experimentally determines the effect of orifice shapes on the coefficient of discharge. Eight different orifice shapes namely circular, semi-circular, rectangular, elliptical, square, triangular, hexagonal and star shapes are tested in a standard experimental setup under different heads to determine the average coefficient of discharge. Based on the experimental result a correlation is developed connecting coefficient of discharge as a function of the non-dimensional shape coefficient
