A general method for evaluating contraction and drag coefficcients for a two-dimensional flow through a sharp-edged orifice or past a prism symmetrically located in a rectangular conduit is presented. The method is based upon the free-streamline analysis and uses a sector hodograph to cover orifices with various nozzle angles and a Joukowsky transformation to transform a line integral in a complex plane into a definite integral. The same method is applied to predict the pressure distribution on the surface of the prism. Both the predictions and the computed coefficients are in close agreement with the previous findings and with the present experiments.
