A Brayton cycle is used to produce power. Air flowing at 40 lbm/s enters the compressor at one atmosphere and 60°F and exits the compressor at 10 atmospheres. The compressor isentropic efficiency is 80%. The air is then combusted with fuel such that the turbine inlet temperature is 2200°F. The turbine isentropic efficiency is 85%. Using the "constant specific heats" method, and assuming air properties for the combustion gas which has the same flow rate as the air entering the compressor, determine the following: The compressor outlet temperature, The compressor power consumed, The turbine outlet temperature, The turbine power produced, The net power (in megawatts), and The thermodynamic efficiency of the cycle.

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
