Please answer question 7:
A centrifugal pump discharges 500 GPM through a 12-inch diameter
impeller. The fluid leaves the impeller with a
tangential velocity of 17 ft/sec. If water, @ 68°F,
enters the impeller via radial flow (I.E. no whirl), and the inner
radius and thickness of the impeller are
1.75-inches. (Assume a constant thickness of the
impeller) and if the pump speed is 1775 rpm, with a head loss of
4.5-feet. What is the horsepower input to the flow by
the pump?

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...
