Consider a house into which radon is emitted through cracks in the base-ment. The total volume of the house is 650 m3 (assume that it is well mixed throughout). The radon source emits 250 pCi s-1 (pCi, or picoCuries, is a unit proportional to the amount of radon gas, and indicates the amount of radioactivity of the gas). Air inflow and outflow can be modeled as a flow of clean air into the house of 722 m3 h-1 , and an equal air flow out. Radon can be considered to be conservative in this problem.
(a) What is the retention time of the house?
(b) What is the steady-state concentration of radon in the house? Express your answer in units of pCi/L.
Given copper and PVC pipe segments analyze which pipe is morelikely to fail in the modes of Compression, Tension,Shear, Bending, and Buckling. Both pieces are the samesize.
A water treatment plant with a maximum daily flow of 4.4 m3/s is treating surface water with a minimum ambient temperature of -1°C (30°F). The water is coagulated with alum and the alum floc was measured to have a settling velocity of 1.6 m/h at 1..
If inflation pushes the price level up by 10 percent, what will be the real value of your savings? What is the real value of your savings if the price level declines by 10 percent?
A closed system of 0.123kg undergoes a frictionless, quasi-static process along the path PV=C from 100kpa to a final state where the volume is twice the initial volume. During the process 8140 N-m of work is done by the system. What is the final spec..
Find the stress induced in the aluminum rod if, after the gap is closed, the two segments are welded together, and then a leftward force is applied of the same magnitude needed to close the gap. Assume the rod segments remain aligned during loading.
Establish the location of the neutral axis (the horizontal centroidal axis) of the cross section. Draw shear and moment diagrams.
For an intermediate beam in 3 bays by 3 bays (each bay is 20' by 20') floor plan, draw the envelope shear and moment diagrams taking into account effect of pattern loading. show values of maximum shear and moments
A course has true azimuth of 157 degrees 15 minutes and a length of 325 feet. What is the departure of the course
At equilibrium, the air space has a volume of 1 L, a total pressure of 1 atm, and a temperature of 298 K. The i mg of formaldehyde (HCHO, MW = 30 g/mol) is injected through the septum into the water.
Find the mass of air in a closed chamber measuring 35 ft by 20 ft by 10 ft, when the pressure is 17 lb/in^2 and the temperature is 75°F, assuming air to be an ideal gas
Show the cycle on a T-s diagram with respect to saturation lines, and determine (a) the power input to the compressor, (b) the rate of heat removal from the refrigerated space, and (c) the pressure drop and rate of heat gain in the line between th..
A concrete beam that is simply supported sustains a uniform live load of 1.8 kips/ft and a uniform dead load (not including self weight) of 1 kips/ft on a span of 24 ft. Determine the layout for a set of No.3 U-stirrups with Fy=60 ksi and F'c=3.5 ..
