Document Summary

1. 1-1. 7 the solutions for these problems are the solutions for problems 1. 1-1. 7 in the 2nd edition solutions manual. 1. 8 the washing machine is a batch reactor in which a first order decay of grease on the clothes is occurring. The integrated form of the mass balance equation is: Next, calculate the grease remaining on the clothes after 5 minutes: ktmm e. The grease that is not on the clothes must be in the water, so. 1. 9: a mass balance around control volume (c. v. ) at the downstream junction yields. 0. 112 mg/l: noting that qb = q0 qf and qs = q0 qf/2 the mass balance becomes and solving for the maximum qf yields (qf/2)cf + (q0 qf)c0 = (q0 qf/2)cs. 1. 10 write a mass balance on a second order reaction in a batch reactor: 0 t calculate mt=1 based on the equation"s stoichiometry that. 1 mole of methanol yields 1 mole of carbon monoxide and.
