Please consider a poorly insulated compressor that was in need of maintenance. The compressor consumed 1.00 kW and took in R-22 at -15 C and 1 bar. The R-22 exited at 10 bar. Irreversibilities within the compressor generated entropy at the rate of 0.100 kJ/kg-K. The compressor leaked heat at the rate of 8.19 kJ/kg at an effective temperature of 300 K.

a. Please take the Compressor as the system and make a sketch. Also, please use this space to keep a list of the assumptions you make while addressing Parts b-g of this problem.   

b. What type of system is the compressor? Please use a sentence or two to explain.   

c. Please write and reduce the Mass Rate Balance (Eq. 4.2) for the system.

d. Please write and reduce the Energy Rate Balance (Eq. 4.15) for the system.

e. Please write and reduce the Entropy Rate Balance (Eq. 6.34) for the system.

f. Please determine Te in C

g. Please determine ?̇ in kg/sec.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26oC with a volumetric flow rate of 0.18 m3/s. Refrigerant exits at 8 bar, 70oC. Changes in kinetic and potential energy from inlet to exit can be ignored. Determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kW.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -20oC with a volumetric flow rate of 0.18 m3/s. Refrigerant exits at 9 bar, 70oC. Changes in kinetic and potential energy from inlet to exit can be ignored. Determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kW.

Maintenance of Production Facility A production facility has several 3-D printing machines which need maintenance for two reasons. Maintenance type A: a sensor may have detected a fault, e.g. an oil leak. Maintenance type B: the quality of the printed product is unacceptable. Each maintenance requirement occurs at random and independently of other requirements for maintenance, with characteristics summarized in the following table: Maintenance Type Average rate of occurrence per week totalled over all 3-D printing machines in the production...
