1. The problem statement, all variables and given/known data See attachment please (Note: a lot of extra information is given, all of the information given for the compressor is possibly redundant). 2. Relevant 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)^(y-1/y).. (where y = gamma = 1.4) 3. 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.
