Eleven moles per second of a pentane (1) + benzene (2) system entering at 40 °C and 1500 mmHg is flashed at 40 °C and 500 mmHg. The mixture entering the flash evaporation unit is 40% by mole pentane. Estimate the molar flowrate and composition of the resulting phase(s) exiting the flash evaporation unit. Note the following information: • P1sat(40 C) = 867.07 mmHg • P2sat(40 C) = 182.64 mmHg • The liquid can be modeled by the 2-parameter Margules equation at this temperature, with the following parameters: A12 = 0.6564 A21= 0.5832
