Refrigerant-134a enters a compressor at 180 kpa as a saturated vapor with a flow rate of 0.35 m3/min and leaves at 900 kpa. the power supplied to the refrigerant during the compression process is 2.3 kw. what is the temperature of r-134a at the exit of the compressor?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
