I have to confess, I have fun razzing you.. :P .... or yanking on your chain... I hope it does give you a chance to learn more... ...and in turn, we learn more from you.
Thanks again for being such a good sport UF !
Speaking of razzing you....in your above math problem....you went against Mr. Oppenheimer's advice, and 'assumed' the dust was 2 mm.
Their dust goes through a 2500 screen mesh, which means the particles should only be .005 mm, not the boulder size you used .
Could you please re-work your math ? :P ...
