Parts arrive at a machine shop with EXPO (25) interarrival times (all times are in minutes); the first part arrives at time zero. The shop has two machines, and arriving parts are assigned to one of the machines (50% probability). Except for the processing times, both machines operate in the same fashion. When a part enters a machine area, it requires operator attention to set up the part on the machine (there is only one operator in the shop). After the part is set up. The machine can process it without the operator. Upon completion of the processing, the operator is once again required to remove the part. After completion, the parts exit the system (parts have to go to only one machine). The same operator does all setups and part removals, with priority given the machine waiting the longest for an operator. The times are as below: Machine number Setup Time Process Time Removal Time
1 TRIA (8, 11, 16) TRIA (20, 23, 26) TRIA (7, 9, 12)
2 TRIA (5, 8, 14) TRIA (11, 15, 20) TRIA (4, 6, 8)

Required:
Run the simulation for 25,000 minutes, and observe statistics on machine utilization, operator utilization.

Aheat pump with refrigerant-134a as the working fluid is used to keep a space at 25°c by absorbing heat from geothermal water that enters the evaporator at 500c at a rate of 0.065 kg/s and leaves at 40°c. the refrigerant enters the evaporator at 20°c with a quality of 23 percent and leaves at the inlet pressure as saturated vapor. the refrigerant loses 300 w of heat to the surroundings as it flows through the compressor and the refrigerant leaves the compressor at 1.4 mpa at the same entropy as the inlet. determine: (a) the degrees of subcooling of the refrigerant in the condenser, b)-the mass flow rate of the refrigerant . (c) the heating load and the cop of the pump, and d)-the theoretical minimum power input to the compressor for the same heating load.
