Question:
The high-velocity exit flow in Example 15.7 is at 183 K. Can that flow be used to cool a room?
Transcribed Image Text:
Example 15.7 A converging-diverging nozzle has an exit area to throat area ratio of 2. Air enters this nozzle with a stagnason pressure of 1000 kPa and a stagnation temperature of 360 K. The throat area is 500 mm2. Determine the mass rate of flow, exit pressure, exit temperature, exit Mach number, and exit velocity for the following conditions: a. Sonic velocity at the throat, diverging section acting as a nozzle. (Corresponds to point d in Fig. 15.13.) b. Sonic velocity at the throat, diverging section acting as a diffuser. (Corresponds to point c in Fig. 15.13) FIGURE 15.13 Nozzle pressure ratio as a function of back pressure for a reversible, convergent-divergent nozzle. • PE PB Throat P
