Sergio's Comments

i sent you this last week:

Sergio !!!

A wonderful Easter to you and all that is yours !

Come now spring with its green and of wondrous attire

May your deeds and dreams be what you ever aspire

Your name will ring fondly across country and shire

And god and his angels grant thou all you desire

Have a great holiday, hope to catch you on the chatroom soon.

Sergio

Thank you very much  for add me...Nice to meet you!

Hello Sergio.Great to hear from you.  Bernoulli & his theory kept me in the air for some 15`ooo hours altogether. As gas velocity increases,its static pressure decreases(at least in Australia!!)  Lift = Cl 1/2 (density)velocity x(s)   surface area.       Density is expressed by the Greek letter roe but I can`t find that on my keyboard.

       All the best.  Alan.
