Question

Fill in the blanks with either < >,=,?, or ? and explain reasons for answer (you can use equations, diagrams, etc.). a. n for an internally reversible power cycle with a m=10 kg/s _______ for an internally reversible power cycle with a m=20 kg/s (when operating between the same two thermal reservoirs) b. ?Q/T ______ (delta)S for an irreversible process c. (delta)S for isothermal expansion _______ (delta)S for isobaric cooling d.(delta)h for an actual compressor _______ (delta)h for an isentropic compressor (for the same pressure rise) e. T(1)_______T(2) , for a reversible turbine with heat loss. **some symbols and letters didn't transfer right with the copy and paste so i tried to create notations: (delta) is the triangle T(1) is initial and T(2) is final n in a) is supposed to be greek

Explanation / Answer

(a) = sol: From carnot second theorem:- Efficiency of all reversible engines working between the same two reservoirs are always equal.

(b) < From Principle of entropy change.

(c) > Since for isothermal condition (delta S) =0 and For Iso baric cooling (delta s)<0

(d) < Because for actual compressor there may be any irreversible can takes place.

(e) = since reversible.
