mixing tank separable differential equations examplesmixing tank separable differential equations examples when studying separable differential equations, one classic class of examples is the mixing tank problems. here we will consider a few variations on this classic. example 1. a tank has pure water flowing into it at 10 l/min. the contents of the tankmixing problems with many tanks cuni.czboth tanks are known and that we have a perfect mixing in bothtanks,nd theconcentrations in both tanks after a given period of time. does the problem sound familiar? similar mixing problems appear in many differential equations textbooks (see, e.g., [3], [10 ], and especially [ 5], which has an impressive collection of mixing problems).4. [applications, modeling, word problems of firstorderlet us go ahead and get started with some examples, first examples in mixing problem, we have a 100 gallon tank that is initially full of pure water and what we are going to do is pour saltwater into the tankspring 06 process dynamics, operations, and control 10o is related to three inputs, each through a firstorder transfer function. 5.3 response of system to step disturbance suppose the tank is disturbed by a step change Δt1 in temperature t1. we have studied firstorder systems, so we already know what the firstorder step response looks like at the time of disturbance td, the output t o willweek 2 notes a mixing problem example1. a mixing problem example the standard mixing problem is the following. we wish to measure the amount of stu (salt) in a well mixed container (pond). we know whats going into the pond, how much salt was initially in the pond, and how fast this stu is coming out. the unknown wed like to solve for is x(t) amount of salt in tankdepartment of civil engineering lafayette collegethe sewage input, what biodegradation reaction rate coefficient (d1) must be achieved for a first order reaction.
