Question 1 of 205eccef9dbacbc34ba4d45f50

According to the data provided in the illustrated table, if the low side saturation temperature is maintained at -15°F and the high side saturation temperature is maintained at 100°F, what is the compression ratio of the system's compressor? See illustration GS-RA-23.

🔍 Key Concepts

• Use the table to find the saturation pressure (psia) at -15°F and at 100°F • Compression ratio for a vapor‑compression system is usually discharge absolute pressure ÷ suction absolute pressure • Be careful about absolute pressure (psia) vs gauge pressure (psig) when picking a numerical ratio

💭 Think About

• Which specific column in the table do you need to read at -15°F and at 100°F to get the values for the ratio? • Once you have those two pressures, what is the simple one‑step calculation you perform to get a ratio? • Looking at the answer choices, which ones look realistic for a refrigeration compressor operating between these two temperatures?

✅ Before You Answer

• Confirm that the pressures in the table are in psia (absolute), not psig • Write down the exact pressure at -15°F and the exact pressure at 100°F from the illustration before doing any math • After dividing high‑side pressure by low‑side pressure, double‑check that your ratio is within a reasonable range for a refrigeration compressor and closely matches only one choice
