Abstract
The purpose of this study is to show the determination of drag coefficient in polygonal plates. The shape of polygonal plates were equilateral triangle, square and equilateral pentagon. The drag of plate was measured by using a load-cell at Reynolds number(Re) about 3.0×10^4 to 6.0×10^4. The drag of polygonal plate was compared with the drag of circular disk, which has same area with polygonal plate. The determination of drag coefficient in polygonal plates was showed by using the number of corners of the plate as a parameter.
