The house has a dirt-floor crawl spaces (1m high). The emission rate of radon into the crawl space is 0.6 pCi/m^2-s. An exhaust system was added to provide 1 air exchange per hour (ACH) in the crawl space. The outdoor concentration of radon is 1 pCi/L. Estimate the radon concentration in the crawl space(in pCi/L).
Note, no other demensions were given.
The routes are currently in user equilibrium. A reconstruction project on route 1 reduces capacity to 3.0 kvph, but total travel demand is unaffected. Field studies note a 35.28 sec increase in average travel time
aluminum foil used to package food is approximately 0.001 inch thick. assume that all of the unit cells of the aluminum are arranged so that a is perpendicular to the foil surface.
Two piezometers are located 1000 ft apart with the bottom located at depths of 50 ft and 350 ft, respectively, in a 400-ft-thick unconfined aquifer. The depth to the water table is 50 ft in the deeper piezometer and 40 ft in the shallow one.
The suspended load exerts a force F = 600 lb at A and bar OA weighs 200 lb. Assume that the bar’s weight acts at its midpoint. Determine the tensions in the cables and the reactions at the ball and socket support O. Draw complete FBD(s) for full cred..
The U.S. Department of Energy (DOE) constructed a Darrieus vertical-axis wind turbine in Sandia, New Mexico. The machine is 60.0-ft tall and 30.0-ft in diameter, and swept an area of 1200 ft 2.
A 400ft equal-tangent sag vertical curve has its PVC at station 200 + 00 and elevation 250ft. The initial grade is -5.0% and the final grade is +2.5%. Determine the elevation of the lowest point of the curve.
The concrete post (Ec=3.6*10^6 psi and Ac= 5.5*10^-6/degrees F) is reinforced with six steel bars. each of 7/8-in diameter (Es=29*10^6 psi and As=6.5*10-6/ degrees F).
a railroad car that weighs 20000lb is traveling eastward with a velocity whose magnitude is 5 fps. a second car on the
Assume Stoke's Law holds true for the following question. You are asked to desgin a settling basin. Flow rates are 16 million gallons/day. The basin must be 4m deep, and 4m wide. Particle size ranges from 0.2-50 mm in diameter.
How many kg/day of NaOH must be added to neutralize a waste stream generated by an industry producing 90.8 million g/day of sulfuric acid, if 0.1% of the sulfuric acid produced is lost to wastewater The wastewater flow is 750,000 L/day
A 300 N force is applied at A. Determine (a) the moment of the 300 N force about D, (b) the magnitude and sense of the horizontal force applied at C that creates the same moment about D,
On a certain highway a -6% grade meets a +2% grade at station 70 + 00, elevation 550.97 ft. An equal tangent vertical curve, 800 ft. long, is to be installed to connect these two grades.
