1. Homework Statement
Derive a relationship between dq/T , dT/T, dp/p , Cp , and R for an ideal gas.
2. Homework Equations
dQ = dU + dW and/or dq = du + dw (for a unit mass)
p*d(alpha) = dw (alpha = specific volume V/m)
du = Cv*dT
p(alpha) = RT (Ideal gas equation, a different form)
Cv + R = Cp
3. The Attempt at a Solution
I went through the derivation and got the following:
dq = Cp*dT - R*T*dp/p
I have no clue what to do from here. Any help? Or is this correct?
