Question

A gas engine that operates on a Brayton cycle has an efficiency of 0.25. On a cold day, the temperature of the air drawn into the engine is 267 K. Part A What is the temperature of the air exhausted from the engine

Answer 1

356K

Step-by-step explanation:

use this formula for brayton cycle

∩=1-(Tin/Tout)

where

∩=efficiency

Tin= inlet temperature

Tout= outlet temperature

solving

Tout=Tin/(1-∩)

Tout=267K/(1-0.25)

Tout=356K
