Peter,
I'm thinking part two of the question would be better answered by proper aviators, and not the pond life. I bet, even now, Danny can offer some figures that would help you out ?

Seems a wierd question as both answers must depend on several variables, speed, aerosol section, overall drag at speed etc etc.! I suspect one of those 1/2 rho V2 S Cd type equations might have the answers.
