Question

What 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?

a. 37 psigb. 87 psigc. 157 psigd. 207 psig

Answer 1

The approximate pressure is: b. 87 psig

Step-by-step explanation:

When we have the temperature (80°F) and the name of the substance (R-134a), we should look for the chart that relate pressure and temperature variables, the chart is attached to the answer, where you will see that a substance R-134a to temperature of 80 °F have a pressure equal to 86.80 Psig.
