Question

The converging-diverging flow domain is shown in Figure 1. The inlet diameter is 0.2 m, the throat diameter is 0.15 m, and the outlet diameter is 0.24 m. The axial distance from the inlet to the throat is 0.30 m—the same as the axial distance from the throat to the outlet. At the inlet section, the stagnation pressure P0 is set to 220 kPa (absolute), while the stagnation temperature T0, at the inlet is set to 300 K.

Various fluids are going to be tested as the working fluid with their density, viscosity,
specific heat capacity, universal gas constant, and specific heat constant. The various fluids
properties can be obtained from books or other related sources and should be registered
in Table 1.
