Extracted text: Q2: A stream of liquid water at a rate of N lit/s with a stream of methanol and ethanol mixture (contains 25 mol% methanol) are fed to continues evaporator. Another stream of methanol at a molar flow rate of G that of the alcohol mixture stream is fed to the same unit. If the liquids are evaporated totally and the produced vapor stream contains (0.1*G) mol% of water at a pressure of 28 psi and 220 °F, calculate: 1- The flow rate and composition of all streams in a molar, mass, and volumetric basis 2- The average molecular mass of all streams The Specific gravity of methanol is 0.762 and that of ethanol is 0.789 while the density of vapors can be estimated as: p = P*Mw/R*T where R=0.082 atm.m/kmol.K.
