Question
A constant-area duct that is 20 cm in length by 2 cm in diameter is connected to a reservoir
through a converging nozzle, as shown in Figure 9.13. For a reservoir pressure and tem-
perature of 1 MPa and 500 K. determine the maximum air flow rate in kilograms per sec-
ond through the system and the range of back pressures over which this flow is realized.
Repeat these calculations for a converging nozzle with no duct. Assume that fis equal to
0.032 and that y- 1.4.
