Draw and label the given stream and derive expression for the indicated quantities in terms of labeled variables. the solution of part (a )is given as an illustration. A continuous stream contains 40.0moles% benzene and the balance toluene. Write expressions for the molar mass flow rate of benzene, nb(mol C6H6/s and mb (kg C6H6/s), in terms of the total molar flow rate of the stream, n (mol/s). The feed to a batch process contains equimolar quantities of nitrogen and methane. Write an expression for the kilogram of nitrogen in terms of the total moles n(mol) of the mixture. A stream containing ethane, propane and butane has a mass flow rate of 100.0g/s. Write an expression for the molar flow rate of ethane, nE (lb-mole C2H6/h), in terms of the mass fraction of this species, xE. A continuous stream of humid air contains water vapor and dry air, the latter containing approximately 21 mole% O2 and 79% N2. Write expression for the molar flow rate of O2 and for the mole fraction of H2O and O2 in the gas in terms of n1 (lb-mole H2O/s) and n2 (lb-mole dry air/s). The product from batch reactor contains NO,NO2, and N2O4. The mole fraction of NO is 0.400. write an expression for the gram-moles of N2O4 in terms of n (mol mixture) and yNO2 (mol NO2/mol)
