The evaporating pressure is 76 psig for r 22 and evaporator outlet temperature is 58 degree f. what is evaporator superheat for this system?

The evaporator superheat for this system would be 18°F. This is calculated by subtracting the evaporator outlet temperature of 58°F from the saturation temperature of the refrigerant at 76 psig, which is 76°F. The difference between the two temperatures gives the evaporator superheat.
