3. Consider a new 1800 MW power plant that burns dry sub-bituminous coal in a PC-wall-fired,
wet bottom furnace with plant efficiency of 39%. Use the emission factors in your lecture
notes to determine the emission rates of all particulates, PM10, SOx, NOx and CO in ton per
year. No gas treatment equipment was installed.
1. The particulate emissions were measured from a factory stack. The stack was divided into
three sectors with different cross-sectional areas. The measured velocities and particulate

- An urban county with an area of 1,000 mile² has an estimated 18 million miles of vehicular traffic per day and has a large power plant. The power plant produces 350 MW of electricity at an efficiency of 39%, burning 10,000 Btu/lb coal. The vehicle emission factor for VOCs is 6 grams/mile; the coal-fired boiler emission factor for VOCs is 1.4 lb/ton coal; biogenic emission of VOCs is 0.4 kg/km²-hr on the average. Determine the total emissions of VOCs in tons/day from all sources (mobile, power plant, and biogenic).arrow_forwardFor automobile, gasoline is a complex mixture of relatively volatile hydrocarbon blended for use in spark-ignition engines. Every time fuel is burned, the carbon is converted to carbon dioxide (CO2), the natural end product of combustion. If we approximate the chemical formula for gasoline by the compound octane (C8H18) with a density of 739 grams/liter, the stoichiometric reaction for complete combustion is: C8H18 + 12.5O2 8CO2 + 9H2O Thus, for every mole of C8H18 fuel that is burned, eight moles of CO2 are produced, along with nine moles of water vapor. Estimate the CO2 emission in grams per mile for a car getting 12 km/liter of gasoline.arrow_forwardThe farming plan of steel structure has 30 ft long simply supported beams spaced at 8 ft apart. The beams carry dead loads (D) and live loads (L). The selected beam size is W 18x50. 1) Based on 0.3Fy allowable stress limit due to dead loads only (D), what will be the maximum D load in psf that can be applied to the beams? Ignore beam weight. 2) Using the D load obtained from Part 1 and based on 0.6Fy allowable stress limit due to combined dead loads and live loads, what will be the maximum live load L in psf that can be applied to the beams? 3) If the maximum mid span deflection due to live loads (L) is L/360 ( or 1.0 in in this case), what will be the maximum L load in psf that can be applied to the beams?arrow_forward

They are designed to get you out of your classroom or office and develop the skills of designing experiments and collecting data, and then performing calculations, evaluating the results, and communicating your findings. Labs are more than just number crunching - they are about reflecting on what is both practical and technically sound engineering problem-solving. For each problem below, address the scenario presented and develop engineering solutions. Communicate your results using drawings, pictures, and discussion, supported by calculations developed using the Microsoft Equation Editor or similar tool. Submit your lab report in a single pdf file uploaded to the location provided in Canvas before the due date/time indicated. Each problem should be treated as a micro-report with a problem…arrow_forwardHow can a construction estimator gain experience to better judge appropriate contingency amounts?arrow_forward
