INTERNAL COMBUSTION ENGINES Practice Problems ME 436 A 3 cylinder, 2.7 liter SI engine operates on a 4 stroke cycle at 3300 RPM with a compression ratio of 8.6:1. At the start of the compression stroke, the temperature is 47°C and the pressure is 82kPa. Assume 3% residual gases. The mechanical efficiency is 81%, combustion efficiency is 96%, and the air-fuel ratio is 16.3, and the fuel heating value is 43,000 kJ/kg. The combustion process starts at TDC and is...

1. Exhaust gas at 400 C and 1 bar from i engines flows at the rate of 125 mol s into a waste-heat boiler where saturated steam in generated at a pressure of 1200 kPa. Water enters the boiler at 20 C (Ta) and the exhaust gases are cooled to within 10°C of the steam temperature. The heat capacity of the exhaust gases is C/R-3.341.12x10 T/K. The steam flows into an adiabatic turbine and exhausts at a pressure of 25...

1. Calculate the primary NAAQS concentration limit for 502 in units of ug/m' at standard temperature and pressure (STP:T - 25*C, P = 1 atm). 2. Fuel X9-6000 is 95.8% efficient in an airplane engine. The unburned fuel leaves as VOCS in the exhaust. For each kg of fuel X9-6000 (Molecular Weight, MW-98), the engine exhausts 20 kg of gases (MW = 28 g/mol). What is the fraction of VOCs in the exhaust (ppm)? ncinerator burns 30 tonnes of plastic...
The absolute pressure at the bottom of a liquid store tank that is vented to the atmosphere is given by: Pabs,bottom = ρgh + Poutside Where: Pabs,bottom = the absolute pressure at the bottom of the storage tank (Pa) ρ = liquid density (kg/m3) g = ac
The absolute pressure at the bottom of a liquid store tank that is vented to the atmosphere is given by: Pabs,bottom = ρgh + Poutside Where: Pabs,bottom = the absolute pressure at the bottom of the storage tank (Pa)ρ = liquid density (kg/m3)g = acceleration due to gravity (m/s2)h = height of the liquid (m)Poutside = outside atmospheric pressure (Pa) Find Pabs,bottom in SI units if ρ = 1000 kg/m3, g = 32.2 ft/s2, h = 7 yd, and Poutside = 1 atm• Here are some tips to help you get started:o Remember your comment section and variable definitions o Use...

Lab 8: Exercises EXERCISE 8.1 GM is a 20 y/o male who was admitted to the ICU for severe closed head injury and multiple fractures resulting from a fighting engagement at the bar on his birthday. According to his friends, his Ht is 178 cm. His measured Wt at admission is 76 kg. His lab values were normal except for low Hgb and Hct due to bleeding (which was well controlled). He was unconscious, thus was tube fed for one...

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...
