a) Explanation Using ideal gas equation of state to obtain the temperature of the refrigerant ( T ) . T = P v R (I) Here, pressure of the refrigerant − 134 a is P , specific volume of the refrigerant − 134 a is v , and gas constant of the refrigerant − 134 a is R . Conclusion: Refer Table A-1E, “Molar mass, gas constant, and critical-point properties”, obtain the gas constant of refrigerant − 134 a ( R ) as 0.1052 psia ⋅ ft 3 / lbm ⋅ R . Substitute 400 psia for P , 0.1384 ft 3 / lbm for v , and 0 b) To determine The temperature of the refrigerant using generalized compressibility chart. c) To determine The temperature of the refrigerant using the refrigerant tables.

A gas mixture with a molar analysis of 40% CH4 (methane) and 60% air enters a control volume operating at steady state at location 1 with a mass flow rate of 5 kg/min, as shown in the figure below. Air enters as a separate stream at 2 and dilutes the mixture. A single stream exits with a mole fraction of methane of 5%. Assume air has a molar analysis of 21% O2 and 79% N2. (CH4, Air) m₁ = = 5 kg/min Air (21% O2, 79% N₂) 3 + (5% CH4, 95% Air)
