Pipes transporting domestic waste can get clogged due to solid particles slowly accumulating on the inner walls of the pipe. The objective of this question is to build a simple model to estimate how clogging affects the magnitude of the primary losses in such a pipe. We consider a cylindrical pipe of length L, initial diameter Do and initial roughness Eo. Waste, assumed to be a Newtonian liquid of density ρ and dynamic viscosity μ, circulates in this pipe at...

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...
