Time to fill a tank! [closed]












-1












$begingroup$


I’ve been desperately trying to come up with some type of formula I can use to help me at work. This is the scenario.



I have a tank that is drafting at 700 barrels per hour(bph). It currently has 4000 barrels of room. I have the ability to fill the tank at 3200 bph, making the tank build at a rate of 2500bph. It is currently 12:00pm, and I want the tank to finish filling at 4:00pm. At what time do I start filling the tank?



I’ve been struggling for weeks trying to figure out a quick formula I can plug in the times and build/draft for tanks so I can use in the future. Any help would be great!

          You will remove $2800$ from the tank between $12:00$ and $4:00$ (presuming it doesn't go dry), so you need to supply $4000+2800=6800$ to fill the tank. That takes $frac {6800}{3200}=2frac 18$ hours. So start that long before $4:00$, which is at $1:52:30$.

                    An IMO inspired problem

                    Image
                    14 4 This problem from IMO 1988 is said to be one of the most elegant ones in functional equations. Problem : The function $f$ is defined on the set of all positive integers as follows: begin{align} f(1) = 1, f(3) &= 3, f(2n) = f(n), \ f(4n+1) &= 2f(2n+1) - f(n), \ f(4n+3) &= 3 f(2n+1) - 2f(n) end{align} Find the number of $n$ with $f(n) = n, 1 leq n leq 1988$. The main idea towards the solution is realizing that these conditions stand for the fact that $f(n)$ just reverses the digits in the binary representation of the number $n$. So, essentially the solution is finding the number of binary pallindromes $leq 1988_{10}$. My question is the following : How to reformulate the problem so that $f(n)$ reverses the digits of $n$ in its ternary representation. Or even better, can we reformulate it for a

                    Has there ever been an instance of an active nuclear power plant within or near a war zone?

                    Image
                    36 3 The question Has there ever been a military combat going on around an active (running or in outage but not decommissioned) commercial nuclear power plant? Or dangerously near it? If yes, how did the plant and its personnel fare in such situation? Why I ask Let's assume for the scope of this question modern commercial nuclear power plants (CANDU, PWR, BWR of generation II plus all of gen III and newer) are usually reasonably safe to operate given that the engineering has been done right and there is a whole cohort of very well trained personnel on-site at all times, well rested and with considerable resources on their hands. Things hard to get with an armed conflict like the recent Syrian war raging around. I can't seem to find any reference or a comprehensive article about this, hence this question.
