Homework Statement
See attachment please (Note: a lot of extra information is given, all of the information given for the compressor is possibly redundant).
Homework Equations
1) SFEE (steady flow energy equation): q + W = (h2  h1) + c2^2  c1^1/2000 + g(z2  z1)/1000
2) Isentropic relationship: T2/T1 = (p2/p1)^(y1/y).. (where y = gamma = 1.4)
The Attempt at a Solution
Apply the SFEE to find T2, but how?
I have tried the following:
q + W = (h2  h1) + c2^2  c1^1/2000 + g(z2  z1)/1000.. where W = 0 (no shaft used), c2^2  c1^1/2000 = 0 (no velocity information provided) and g(z2  z1)/1000 = 0 (no change in height).
Therefore: q = (h2  h1)
q = cp (T2  T1).. where cp = 1.01kg/K, and cp (T2  T1) is (h2  h1) for an isobaric process.
Multiplying both sides of the equation by mass flow rate (so that the power given (i.e. heat) can be used in the equation).
q x m = heat energy [kW].
I get an answer of 5229.3 degrees C. (convert units to Kelvins during calculations).
Thanks in advance.
Koen.
