turboprop engine

Consider a turboprop engine in which the turbine powers the compressor and a propeller. Assume the same cycle as in Problem 10.46, with a turbine exit temperature of 900 K. Find the specific work to the propeller and the exit velocity.

 

Problem 10.46

 

The Brayton cycle in Problem 10.21 is changed to be a jet engine. Find the exit velocity using cold air properties.

 

Problem 10.21

A large stationary Brayton cycle gas-turbine power plant delivers a power output of 100 MW to an electric generator. The minimum temperature in the cycle is 300 K, and the exhaust temperature is 750 K. The minimum pressure in the cycle is 100 kPa, and the compressor pressure ratio is 14:1. Calculate the power output of the turbine. What fraction of the turbine output is required to drive the compressor? What is the thermal efficiency of the cycle?
