Benzene is evaporating at the rate of 1 gram/min into a room (6m
x 6m x 3m in size) and a ventilation of 10m3 / min
a.How to know whether it is a rate change of mass balance or a
difference form?
b.Compute steady state of benzene concentration in the room
c.Compute time necessary for benzene to reach 95% of steady state
(assuming air in the room is initially free of benzene)
Thank You.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
