It has been estimated that the emission of NOx from a coal fired power plant is 1300 g/s. At 100 km downwind (y=10m), what is the concentration of NOx in g/m^3. The wind speed at the top of the stack with a height of 100m is 6.5 m/s and an inversion layer of 750m
Pressure air = 95kPa
Temp. air= 25 degree C
Cloud Cover: few broken clouds (partly cloudy)
Stack temp. = 305 degree C
Diameter= 5m
Exit velocity= 1.5 m/s
time= 10:00 am summer day
plume rise = 11.7m
In equation (1) notice that y plays the role of the independent variable; hence, solving it yields w(y). Then substituting w(y) into (2) we obtain a separable equation that determines y(x).
The pavement is on a base which has a modulus of subgrade reaction of 250 pci. A 17,000 lb corner load is applied (al is 7 inches). Using the revised Westergaard equations, find the modulus of elasticity of the pavement if a corner deflection of 0..
Determine a set of a rectangular beam design values b,d and As that will be needed to support a factored bending moment Mu= 450 Kip-ft. Use f'c= 4500 psi and fy= 40000 psi.
A reservoir with a length of 20 km and width of 3 km has a flood inflow of 1000 m^3/s. (a) If exit flow is restricted to 500 m^3/s, how fast is the water level rising in the reservoir per day
The student strikes the sign at a speed of 25 mi/h. if the student was travelling at 65 mi/h when the sign was first spotted, what was the student's associated perception reaction time
5,000 gpd of primary sludge at 5% solids (50,000 mg/l) and 5,000 gpd of biological treatment sludge (10,000 mg/l) are blended, then thickened to 8% solids. What volume of supernatant is returned to the reactor
A small parking lot at a neighborhood park has 5 parking spaces, and the number of occupied slots at 9 AM is a binomial random variable, with p=0.75. If vehicle arrivals at the lot follow a poisson process, with arrival rate lambda
For unidirectional carbon/epoxy tape at a 60% fiber volume fraction, calculate E11 and E22. Given Ef= 211 GPa and Em =10 GPa. Calculate the fiber weight fraction. Given pf=1.95 g/cm3 and pm =1.3 g/cm3.
Using a design speed of 50 mi/h, determine the stations and elevations of PVCs, PVIs, and PVTs of the two vertical curves required to connect the highway segments, as well as the length of the constant grade section (connecting grade is to be as s..
Develop a preliminary design, including flow rates, pipe sizes, and pipe slopes for a trunk sewer to be laid in the development shown in the accompanying figure from 6th to 1st Streets along Peavy Avenue.
A pipe is to be installed under the ground on a bed of aggregate 6 in. thick. The entire weight on the aggregate from pipe and soil above the pipe is 1800 lbs. per linear foot of pipe. What is the pressure on the soil if theta is 45 degrees? Assum..
A cylindrical pressure vessel can support an internal pressure of 2640 psi. The maximum hoop stress is (65000/2) psi and the maximum shear stress is 16000 psi. If the diameter of the tank is 7 inches,what is the minimum wall thickness. If the wall th..
