The tank contains 3 kg of dissolved salt be up to 75 liters of water. Saline solution of strength 0.4 kg of salt / L is pumped into the tank at speed 6 L / min. • Solution is drained from the tank at the same speed. • Set up a differential equation that describes this system. Let's solve the differential equation and get a function that describes the salt content of the tank at time t

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
