Montgolfier's Formula. A formula for estimating the 

 velocity of air. It is as follows : " The velocity in 

 feet per second is equal to eight times the square root 

 of the height through which the body has fallen." 

 This is expressed by the formula. 



y = V 2g(x- 1 + J 2{e _ n ) 



v — The velocity in feet per second. 



g — The acceleration due to gravity, 32.18" feet per second. 

 x — Height of shaft. 

 / — Internal temperature. 

 t' — External temperature. 

 .002 — Co-efficient of expansion for i° F.

 modification, for that of Geoffroy Saint-Hilaire.
