Question

8. (3 points) Consider a “turbocharger,” such as the one modeled in Problem 7-214. Which of the statements below is FALSE? (Select the best response.)

a) If the isentropic efficiency of the turbine is increased, the work input to the compressor will increase.

b) If the isentropic efficiency of the turbine is increased, the outlet temperature of the gases leaving the turbine will decrease.

c) If the isentropic efficiency of the turbine is increased, the outlet temperature of the gases leaving the compressor will decrease.

d) If the isentropic efficiency of the turbine is increased, the isentropic efficiency of the compressor will decrease.

Explanation / Answer

c) If the isentropic efficiency of the turbine is increased, the outlet temperature of the gases leaving the compressor will decrease

because the isentropic effiecency of turnine is increases, the work input to the compressor is increase so that the outlet temperature of the gases leaving the compressor increses
