Cyclic

this specific equation (of motion) does not need mass. use equation: 2 2 Vf = Vi + 2a (x) Vf = ? Vi = 0 a = 9.8m.s x = 200m Vf should = 62.61m.s downwards Does this help?

Displaced, im just blowing air from one room to another room through a small fan...

hi guys Does anybody know what formula one would use to calculate how long it would take to raise the temperature of an area of x litres of air by blowing in y litres of warmer air . ie if I blow in air at 25 degrees C into an area which is at 20 degrees C , how long would it take to raise the temperature by one , two or three degrees? What I know is the volume of air (in litres) blowing in as well as the volume of air in the area (in litres) as well as the two different temperatures of both of these areas. Thanks guys:-)
