A power plant emits 95 g/s of SO2 from an effective stack height of 60 m. The wind speed is 3 m/s and the solar insolation is slight.
A) Estimate the ground level SO2 (ug/m^3) at a point 4 km directly downwind of the power plant
B) Estimate the ground level SO2 (ug/m^3) at a point 2 km downwind and 0.6 km off the axis
C) If the temp is 10 C and the pressure is at 1 atm, does the air quality of A and B meet the NAAQS requirement of 0.14 ppm?
The grains of wood in the board make an angle of 20 degrees with the horizontal as shown. Determine the normal and shear stresses that act perpendicular and parallel to the grains if the board is subjected to an axial load of 250 N.(Dimensions l=3..
An inverting amplifier is implemented with a R1=10 kilo Ohms and R2= 100 Kilo Ohms, and an op amp with finite open-loop gain a=10^3 V/V. Sketch and Label Vi,Vo,and Vn versus time if Vi is a 1-kHz triangular wave
The porosity of both media is 0.40, the shape factor for the anthracite is 7.5, and the shape factor for the sand is 6.0. Assume a water temperature of 60 F.
design a horizontal curve with a 40-degree central angle ( delta = 40) for a two-lane road with 11-ft lanes. The design speed is 70 mi/h and superelevation is limited to 0.06 ft/ft. Give the radius, degree of curvature, and length of curve that yo..
The herbicide 2,4,D, is applied to a golf course at a rate of 1.2 kg/ha. The organic matter content of the soil is 1%, bulk density is 1.3 g/cm3, and water content is 0.3.
a rectangular piece of steel is 10" wide by 60" long by 3" deep, what is the max tensile force that could be applied to the steel, and what is the total elongation of the steel
A model grain dryer is being used to investigate the drying process. It is discovered that the load cell which supports the dryer indicates that the mass of the dryer and its contentsinitially increases during the heat-up.
Design a circular radial-flow clarifier for a town with a projected population of 45,000. Assume that the wastewater flow is 400 L/capita-day. Size the system for a 2-hr detention time at average flow.
What are the effects of water pollution on the components of the hydrologic cycle?
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
The 3.0-ft diameter piper is 3,400 feet long with a steady flow rate of 10,000 gal/minozone (in mg/L) should be Injected at the head of the piper so what there will be an ozone concentration of 1.0mg/L
Describe the equation for discharging a water tank. Use: H= 2m, A_s= 1m^2, density water= 1000kg/m^3, K = 1kg hr^-1 m^-1/2 Mass flow in = 0 and mass flow out given by, Mass flow out = K z^1/2.
