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?
Consider friction loss in teh 225-ft-long discharge pipe, but neglect other losses. Then, redesign the system by using a larger pipe size to reduce the energy loss and reduce power required to no more than 5.0 hp.
A-Olympus Mons, a 69,000-foot-tall mountain on Mars, is the largest volcano in the solar system. Its circumference at the base is large enough to cover almost the entire state of Colorado.
Determine the force required to drag a small barge (10 ft by 30 ft) in a shallow canal (3 inches deep) in order to maintain a velocity of 5 ft/sec. Assume that the fluid is behaving in a Newtonian fashion and the water temperature is 68 degree fah..
The coefficient of friction between a car's tires and the road is such that the car can generate a maximum deceleration of 1.1g without experiencing slip.
A 150 L helium tank contains pure helium at a pressue of 1825 psig. How many 3.5L helium balloons can be filled from the helium in the tank? (Assume an atmospheric pressue (14.7 psia) and a temp of 298K.
Weather records for a certain region indicate that there is a tendency for two hot summers to occur in a row. From the statistics for the region, the following information has been es tahlished
An 8-inch water main with a flow rate of 14 ft3/sec raises 100-feet. At the beginning of the main the pressure is 110 psig and drops to 50-psig at the end. The calculated Hl = 11.7 m.
On your first trip to Planet X you happen to take along a 165 g mass, a 40 cm long spring, a meter stick, and a stopwatch. You're curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth
Find the dimensions of a rectangular concrete channel to carry a flow of 150 m3/s, with bottom slope 0.015, and mean velocity 10.2 m/s.
For an unknown alloy the stress at which plastic deformation begins is 400MPa and the modulus of elasticity is 120GPa. If the original specimen length is 76 mm, what is the max length to which it may be stretched without causing plastic deformatio..
After operating for a period of time, assume that the opening size decreases to 10-mm due to the accumulation of materials (debris) on the screens.
one gallon of paint(volume=3.78 x 10^ -3) covers an area of 25 m^2. what is the thickness in mm. of the paint on the wall
