A bonfire emits CO at a rate of 30 g/s on a clear night (very stable conditions, Class F). The wind is blowing at 2 m/s at the effective stack height of 6 m.
a. You have found a great place to pitch your tent 200 m directly downwind of the fire. Based upon the recommended level for CO of 40 mg/m3, the given conditions, AND the fact that the fire will be burning ALL night, should you find another spot to camp?
b. How would your answer be affected by the atmospheric stability conditions?
a temperature probe moves with the velocity 2i+2j-3k through air. the temperature of air changes as T(x,y,z,t)=(2x^2-3y+z^3)cos(at). Find the rate of change of temperature measured by the probe.
A manometer connects a large water tank open to the atmosphere to a closed spherical tank of air. The manometer contains both oil and water. Find the gage pressure in the tank "A".
Radon from well water may pose a radiological health hazard. One treatment technique is simply to hold the water in storage, allowing the radon to decay. how large must each be to achieve the desired level of control.
