Alrighty, so I got the equation to be: ln(x) + ln(x-10) = -(1/1000)t +C And then if x(0) = 25, I get C= 5.92... or... (x)(x-10) = 5.92e^[-(1/1000)t] Which works because as t approaches infinity x equals 0. But when I use x(0) = 150 I get pretty much the same thing but C is now 9.9...

Thanks! I'll give it a try.

I'm attempting to help someone with their diff eq homework and I'm having trouble remembeing how to do things and their book isn't the best. So here's the problem: "Suppose the number x(t) (with t in months) of alligators in a swamp satisfies the differential equation dp/dt = 0.0001x^2...

Quick clarification- if I'm wanting to know the force on the pipe itself, then I would just have the total weight be the weight of the water? I would only use the weight of the pipe itself if I'm wanting to find the force on the support, correct? As I understand it, all I want is the force on...

Thanks! For some reason I never think to use conservation of momentum. Maybe I should tatoo it on my hand or something.

Thanks! I reposted it here because I thought it might be more of a general physics problem.

Hey guys, I've been reading threads on here for a little bit and now I have a question I need some help with. I tried doing a search, but I didn't really know what I was looking for so it wasn't too successful. But here it is: My boss gave me this question to figure out and I'm not really...

I also have two alternatives to the 90 degree bend. One is a 45 degree slant and the other simply has the pipe end with a blind flange. I've attached pictures of each of these as well. Would I solve these two the same way as the above problem?
