Gas is compressed adiabatically from a suction temperature of 15 °C with a compression ratio of 2. Calculate the rise in gas temperature. γ = 1.4; compressibility factor Z = 1 for both suction and discharge. Take the compression ratio as the pressure ratio P_{2}/P_{1} = 2 (absolute discharge ÷ absolute suction pressure, not a volume ratio) and the compression as reversible adiabatic (isentropic).
