Mixing Salt and Water - First Order Differential Equations
My 200th Video! Thank you for your support. 6.5K subscribers and 1.7 million views as of December 10, 2018. My goal is to double that in 2019. In this video, we use first order, linear, ordinary differential equations to solve a mixing problem. We have a 3000L tank that is being filled and drained at the same time at 10L/min. The solution filling the tank has a salt concentration of 0.02 kg/L, while the tank has an initial quantity of salt of 15kg. Our problem is to find the amount of salt in the tank at any given time. Thanks for watching. Please give me a "thumbs up" if you have found this video helpful. Please ask me a maths question by commenting below and I will try to help you in future videos. I would really appreciate any small donation which will help me to help more math students of the world. Please donate here: https://paypal.me/MasterWu Follow me on Twitter! twitter.com/MasterWuMath
