type i - question # 12\nwhat is the approximate pressure of a storage cylinder of recovered r - 134a that does not contain any non - condensable impurities and is stored in a room where the temperature is 80°f?\na 37 psig\nb 87 psig\nc 157 psig\nd 207 psig
Answer
Explanation:
Step1: Use R - 134a pressure - temperature relationship
For R - 134a, we can refer to its pressure - temperature chart. When the temperature is 80°F, from the R - 134a pressure - temperature chart, the corresponding saturation pressure is approximately 87 psig.
Answer:
B. 87 psig
