In this paper we are concerned with the degree of approximation made when various common parameters involved in an isentropic, compressible fluid flow are evaluated from incompressible relations. First, compressible and incompressible solutions are derived and presented graphically. Then, ratios between these compressible and incompressible treatments are formed which define various expansion factors; these are tabulated and presented graphically. Several numerical examples illustrate the use of the tables and graphs.
