Web1 Answer. Sorted by: 1. It appears there is a mistake made in determining the initial condition for the problem. The initial amount of salt in the tank x ( 0) = 70 kg. As a result, the solution to the differential equation is. x ( t) = 35 ( 1 + e β 0.005 t), where t is in minutes.Finally, by plugging t = 240, we get. x ( 240) = 45.54 kg. WebApr 1, 2016 Β· Will be fixed. The $6$ went away because $$\int6(100+t)^2dt=6\cdot\frac13(100+t)^3+C=2(100+t)^2+C$$ When I took differential equations long ago, I was very lazy and never bought the textbook, never did any problems, and only went to class every week or so with the result that the only kind of β¦
WebI thought for mixing problems there was a formula dx/dt=rici-roco, where ri and ro are rate ins and rate outs and ro and ci and co are concentrations ins and outs. So I had ri=ro=.1L per second (or 6 Liters per minute) and ci as 1 since it was 100 percent nitrogen coming in. Co is defined as x/(vo-(ri-ro)t) where vo is initial volume of the ...
