1. What is the efficiency of the system, if the actual work output from the process is 15 J and work output for a reversible process is 20 J?

2. How long would it take for a reversible process to complete?

3. What is the reversible work done if 4 m3 of an ideal gas is compressed adiabatically pV1.5 = K from 2 Pa to 16 Pa?

4. What is the heat transferred from the system if the enthalpy of the output is 5 J and input is 10 J?

5. In a reactor two stream are entering, one with C6H6 at 10 atm and 27oC, and another with H2 at 10 atm and 0oC, producing C6H12 and H2 at 10 atm and 23oC, what are the total degrees of freedom?

6. What is the efficiency of the system, if the actual work output from the process is 10 J and work output for a reversible process is 40 J?

7. What is the heat transferred to the system if the enthalpy of the output is 14 J and input is 8 J?

8. What is the height difference of the water (density = 1000 Kg/m3), if the change in velocity is 10 m/s and change in pressure is 500 Pa?

9. What are the total degrees of freedom if the number of species are 5, total streams are 2, stream temperature 2, stream pressure 2 and heat released 1?

10. What is the work done by saturated water which evaporates to 20 kPa atmosphere to form 1.5 m3 of water vapor?
