Was that post completly necessary? Oh and btw congrats on the weight loss. Last time I remember seeing you, you were pretty chubba-blub.
Answer said:You will need to understand the basics of differential equations for this one.
Let Vt = V = The volume in the tank at time t.
Let tt = delta t (since I don't know how to display a delta symbol in HTML).
Let Kx = Some constant of integration.
Vt+tt = Vt + 1*tt - (tt/100)*Vt.
dv/dt = (Vt - Vt+tt) / tt = 1 - V/100.
dv = (1 - V/100) dt
100/(100-V) dv = dt
Integrate each side:
-100*ln(100-V)=t + K1
exponentiate each side:
(100-V)-100 = K2 * et
100-V = e-t/100 * K3
V = 100 - K3*e-t/100
We know V=0 when t=0, thus K3=100
V = 100*(1-e-t/100)
Substitute 50 for V and it is not difficult to solve for t=100*ln(2).
The answer is 100*ln(2) seconds =~ 69.3 seconds.
Hey I was only off by a little! And they say weed frys your brain. HA! Still going strong!
How'd you lose all the weight by the way? Subway?
Weed + eating lots of healthy munchies + getting stoned and going to the gym - beer = skinnier Dred
But now that it's getting closer to me joining the USAF I had so stop smoking for drug testing. It's been a little less than a month, and it suuuuuuucks.
So here's a question to get this thread rolling: what's your most amusing stoner story?
Hi
Ok, Rider, this dry spell is so 4 months ago!!!! When???????
Dude, Codi and Gonzo 5......................NOW!
Hi
I'm about to move in with a big time, gay stoner. What should I expect?
