True or False 1) In a Rankine Cycle, real work produced by the turbine is less that the isentropic work. 2) A valve (throttling) and ideal pump both operate isenthalpically 3)For a given TC and TH, the vapor compression cycle has a higher COP than the Carnot cycle. Group of answer choices

If a Diesel cycle and Otto cycle have the same initial conditions, the same compression ratio, and the same temperature at state 4, which will do more work? Defend your answer (a defense can include words, equations, and/or sketches).

Fill in the blank:   The compression in the Otto cycle involves an isentropic process in a closed piston-cylinder assembly, whereas the compression in the ideal Brayton cycle involves an isentropic process in a(n) (Type your answer here) operating at steady state.

For a given Rankine Cycle, the difference between the heat added and the heat rejected is not equal to the difference between the turbine work and the pump work. Group of answer choices a. True b. False

Consider an ideal Brayton cycle operating on air. The inlet to the compressor is 300 K, 100 kPa. The compressor and turbine pressure ratios are 10. The maximum temperature in the system is 2000 K. Treat the air as an ideal gas with constant specific heats. a. What is the efficiency of this cycle? (Note: see derivation in section 10.1) b. What would the efficiency be for a Carnot cycle operating between the same temperature limits? c. You should have found that the efficiency of this cycle is less than the Carnot efficiency. So, there must be some irreversibility and entropy generation. For each of the four processes (compressor, heat addition, turbine, heat rejection), find the entropy generation per kg of air. For this analysis, assume the best-case scenario – heat is transferred to the high-T heat exchanger from a reservoir at 2000 K and heat is removed from the low-T heat exchanger to a reservoir at 300 K. d. If entropy is generated during this cycle, where does it go? e. What is…

3. What are the four major accessories of a Rankine Cycle? Define each.

4. Plot the cycle diagram for the air-standard Carnot cycle operating with 1 lbm of working fluid between 60 and 400 °F, if the maximum volume reached in the cycle is 1 ft3 and the maximum pressure in the cycle is 2000 psia. Plot the P-v, T-s, P-h, and h-s diagrams. Assume that the specific heat of air can be taken as temperature-independent.
