This is a question I have and I am not sure how I am supposed to figure Low side saturation temperature, total superheat exiting the evaporator etc..

R-22 - Refrigerant
Low side pressure = 68.5 psig
High side pressure = 210.8 psig
Discharge line temp @ compressor = 150 deg F
Liquid line temp = 90 deg f
Suction line exiting the evaporator = 52 deg F
Suction line temperature entering the compressor = 65 deg f
Identify all components and appropriate lines example (suction line) on this diagram, also
show where pressures and temperatures should be taken.

Low side saturation temperature __________ deg f
Total superheat exiting the evaporator _________ deg f
Total superheat entering the compressor _________ deg F
Total superheat exiting the compressor _________ deg F
High side saturation temperature _________ deg F
Total subcooling exiting the condenser ________ deg F

If someone could help me out I would be VERY thankful,

Thanks.
