(17 pt) Suppose a bonfire emits CO at the rate of 20 g/s on a clear night when the wind is blowing at 2 m/s. If the effective stack height at the fire is 6 m: (a) (6 pt) What would you expect the ground-level CO concentration to be along the centerline at 400 m downwind (in mg/m3 )? (b) (6 pt) Estimate the maximum ground-level concentration using empirical method (in mg/m3 ). (c) (4 pt) Estimate the maximum ground-level...

2. A power plant emits 300 kg of SO2 per hour into a neutral atmosphere with a wind speed of 2 m/s. The ơy and o, values are assumed to be 100m and 30m, respectively. Taken into consideration of the ground reflection effects: 1). what will the ground level concentration of SO2, expressed in ug/m3, if the town is 2 km off the plume centerline and the plant has a stack that produces an effective stack height of 20 meter?...

A power plant burns coal with 2 % sulfur. Emissions occur through a 70-m tall 02. stack with a diameter of 1.5 m. The exit velocity and temperature are 15 m/s and 340°C, respectively. The atmospheric conditions are temperature of 28°C and pressure of 90 kPa. On a clear summer aftemoon with a wind speed of 2.8 m/s at 10-m level, the ground level SO concentration is measured to be 143 ug/m at a point 2.5 km downwind and 300...

Q4. A large, poorly controlled copper smelter has a stack 150 m high and a plume rise of 75 m. It is currently emitting 1000 g/s of SO2. Estimate the ground-level concentration of SO2 from this source at a distance 5 km directly downwind when the wind speed is 3 m/s and the stability class is C.

URGENT!!
A rural power plant with no fly ash removal equipment burns 300 tons of coal per day. Using the emission rate given in the table 1 for a coal containing 9 percent ash and fired on a spreader stoker, determine the deposition rate for 50 um particles having a density of 1.5 g/cm3 at distances of 1 and 3.5 km downwind from a stack assuming that 10 percent of the emissions are approximately 50 um in diameter. The effective...

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
