Hi Guys/Girls I require your help or assistance with the following Thermodynamics Assignment.
I have a few ideas however my solutions are incomplete.
The assignment questions can be seen below in the image.
I have attempted questions 2 and 3 and would like to know if I'm correct / along the right path.
My solution
__________
2) With reference to the question about the compressor
I've taken 100% efficiency to mean , fully reversible.
assumptions : steady state and adiabatic.
I've assumed that air is an ideal gas throughout the compressor.
change in entropy = 0
change in entropy of an ideal gas = 0 ( to calc the exit temperature of the compressed air )
calculated Delta H = work done by the compressor.
3) With reference to the Turbine question again Ive assumed the same conditions as with the compressor.
My initial thought is to split the mixture going into the turbine and calculate the change in entropy and enthalpy for each substace.
1) Have no idea how to prove this.
