From the table the maximum time taken is for Medical exam and treatment for first visit. This can be expanded double so that time will be reduced to 0.25 for Ivisit and 0.125 for II visit. The reception/discharge can be reduced by 25% so that first visit time = 0.30 and second = 0.15

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. 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.
