Direction: Air enters an adiabatic nozzle at 300 kPa, 500 K with a velocity of 10 m/s. It leaves the nozzle at 100 kPa with a velocity of 180 m/s. The inlet area is 80 cm². The specific heat of air c is 1008 J/kgK
-
The exit temperature of the air is
-
- 516 K
- 532 K
- 484 K
- 468 K
Correct Option: C
| h1 = | = h2 + | ||
| 2 | 2 |
| ⇒ | = h1 - h2 = Cρ(T1 - T2) | |
| 2 |
| &There4; | = 1008 × (500 - T2) | |
| 2 |
⇒ T2 = 484K
