Differential equations modeling: A tank of salt
Web1 Answer. Let x be the amount of salt left in the tank after t minutes. Each minute 6 L of water is pumped into the tank, and 7 L leaves the tank, so overall 1 L of water is drained from the tank. Then after t minutes water left in the tank would be ( 1000 − t) L. Now at t minutes, new 6 L of water is pumped into the tank, so there are 1000 ... WebMar 9, 2024 · Let’s solve some problems based on this equation, so you’ll get a clear idea. Newton’s Law of Cooling Practice Problems. Problem 1: A hot coffee cools down from 90 °C to 80 °C in 5 minutes when it is placed on the table. Calculate the time taken by a hot coffee to cool down from 60 °C to 50 °C. The temperature of the surroundings is ... WebAug 30, 2024 · My calculus teacher says that we should do it using differential equations. Q ′ ( l b / m i n) = 4 ( g a l / m i n) ⋅ 0.005 l b / g a l ( I N) − 5 ( g a l / m i n) ⋅ Q ( l b) / V ( g a l) where V = 100 − t because of the way the tank drains. However, the solution to that doesn't really fit the logic of the problem that well. signs of financial abuse in children
