A reservoir at \( 300 \) K feeds a choked nozzle. The static temperature at the throat is
Answer: D
The throat is at Mach one, so \( T^* = 0.833 \times T_0 = 0.833 \times 300 = 250 \) K. Note that the reservoir temperature is the stagnation temperature, since the gas there is at rest, and it is conserved through an adiabatic nozzle even if losses occur.
