2) Consider a setling chamber to treat a particulate ladened air stream having a volumetric flow rate of 1 m'/s. Design a settling chamber to collect particles 10 um in diameter having a density of 1700 kg/m3. The chamber is to be 1.5 m in width and 1.5 m in height. A) How long must the settling chamber be to give a theoretical perfect collection efficiency? B) Using the length determined (in part a), determine the collection efficiency for 5...

A dilute slurry contains small solid food particles having a diameter of 3 ´ 10-2 mm which are to be removed by centrifuging. The particle density is 1130 kg/m3 and the solution density is 980 kg/m3. The viscosity of the liquid is 1.2 × 10-3 Pa · s. A centrifuge at 4,000 rpm is to be used. The bowl dimensions are b = 100.1 mm, r1 = 6.0 mm, and r2 = 40.0 mm. Calculate the expected flow rate in...

A packed tower is to be used to remove 90% of the ammonia from an air stream containing of 5% of ammonia by volume. The feed gas rate is 100 lb mol/hr at 20 °C and 1 atm. Water at 90 lb mol/hr containing no ammonia is used as a solvent and the packing is 1-inch Raschig rings. Assume the tower is isothermal at 20 °C. It is to operate a 60% of flooding. In addition, for this system m...

You will need graph paper, a calculator, a copy of Appendix I from lesson HTC- 4 2 and access to steam tables to answer this TMA l. A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8) and 15% butene (C,H,) by volume. It is to be fed to the combustion chamber in 10% excess air at 25°C, where it is completely burnt to carbon dioxide and water. The flue gases ane...

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...
