Contest: Cigars ablaze!

[buzz]

and the winner is...

mail man! PM me your addy and I'll get these burned blunts in the mail.

Thanks for playing guys, and for sending me luck back in October. For those of you geeks out there, here is the answer...

Volume of cigars = V = 150 * 2.4 in^3 = 0.21 ft^3
Heat Release Rate = Q = 250*0.21 = 52.5 BTU/s = 55.4 kW
r/H = 2/10 = 0.2
Gas Temperature = Tg = 23.9 + [(5.38)*(55.4/0.6)^(2/3)]/3.1 = 59.4 degrees C = 138.8 degrees F
Plume Velocity = u = [(0.2)*(55.4)^(1/3)*(3.1)^(1/2)]/[(0.6)^(5/6)] = 2.1 m/s = 6.7 ft/s
Response Time = tr = (100)/[(2.1)^(1/2)]*LN[(138.8-75)/(138.8-135)] = 195 seconds

Ahh, the joys of a good heat detection formula... man am I glad I don't have to take that test again.
