Re: [Phys-L] [Phys-l] Poll shows fewer Americans "believe" in global warming

[brian whatcott <betwys1@sbcglobal.net>]

Suppose there are 200 million cars in the US which account for all the 
man made CO2 increase in the atmosphere.
Suppose a tail pipe is 2 inch diameter, and emits 20% CO2 when the 
engine is running, which happens on average 2% of the time.    To 
counter that effect, let's estimate the magnitude of the flux of a gas  
which is 1000 times more potent at cancelling the global heating effect 
than CO2 is at exciting the effect.

We will suppose that the palliative flux is emitted 100 times faster 
than an exhaust flow. What diameter of pipe should we visualize?
sqrt(2E8 cars X PI sq inches tail pipe area X 0.02 duty rate X 0.2 CO2 
fraction X 0.001 potency factor X 0.01 flow ratio X 4/PI pipe diam to 
area ratio )- this provides me a back of the envelope estimate of 6 
inches diameter  for the quenching gas exit pipe diameter.   This is 
certain to be an underestimate. This is described as a garden hose?
