Chapter 2, Problem 30RQ
A gas is compressed inside a compressor's cylinder. When the piston is at its bottom dead center, the gas is initially at 10 psig, 65°F, and 10.5 in3. After compression and when the piston is at top dead center, the gas is 180°Fand occupies 1.5 in3. What would be the new pressure of the gas in psig?
