A centrifugal compressor with a power consumption of 18 kW per 100 cubic feet per minute (cfm) delivers 1000 cfm to a plant air supply. The compressor operates 2080 hour annually. Determine the annual operating cost of the compressor if the annual demand charge is $100/kW-year and the electric energy charge is 0.065 $/kWh.

Please answer all PROBLEM 1 A three-litre four-stroke diesel engine develops 12 kW per m3 of free air inducted per minute. The volumetric efficiency is 82 % at 3600 rpm referred to atmospheric condition of 1 bar and 27 oC. A rotary compressor which is mechanically coupled to the engine is used to supercharge the engine. The pressure ratio and the isentropic efficiency of the compressor are 1.6 and 75 % respectively. Calculate the percentage increase in brake power due...

A small coastal town in Queensland is subject to an increasing permanent population and also a transient influx of tourists during the summer period. Council already receives frequent complaints of restricted water supply. The water supply system comprises a rising trunk main from the treatment plant A to the service reservoir B, the service reservoir, and service mains to the consumption areas. Two consumption areas C and D at different elevations are gravity supplied from the service reservoir. The service...

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...
