What is the compression ratio of a compressor with a suction pressure of 120 psig and a discharge pressure of 480 psig?
A) (480 - 15 ) / (120 - 15 ) = 465 / 105 = 4. 4 to 1 B) (480 + 15 ) / (120 + 15 ) = 495 / 135 = 3. 67 to 1 C) 480 / 120 = 4 to 1 D) (480 ? 120 ) / (480 + 120 ) = 57,600 / 600 = 96 to 1
