Answer:
Step-by-step explanation:
The Brayton cycle is Joule cycle and is the model for the operation of a gas turbine engine.
The general equation for the efficiency of an engine working between two temperatures is:
- Efficiency = 1 - T cold / T hot.
In this case:
- T cold is the temperature at which the air is drawn from the atmosphere into the engine (turbine): 267 K; and
- T hot is the temperature of the air exhausted from the engine (the unknown variable of the problem).
Thus, substituting the data into the formula, you get:
Answer: the temperature of the air exhausted from the engine is 347 K
