A binary feed mixture consisting of 30 mol% methanol and rest water needs to be separated by flashing at 90 °C and 1 atm. The vapour-liquid equilibrium (VLE) data for

the methanol-water system at 1 atm are given in Table 1 [adapted from Perry et al. (1963)]. Using the linear interpolation method and using the information given in Table 1,determine the percentage recovery of methanol in the vapour stream.
