A tank contains 3,000 L of brine with 18 kg of dissolved salt. Pure water enters the tank at a rate of 30 L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate.

A tank contains 3,000 L of brine with 15 kg of dissolved salt. Pure water enters the tank at a rate of 5 L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate. How much salt is in the tank after 60 minutes?

In a tank 100 liters of brine solution containing 50 kg of total dissolved salt. Pure water is allowed to run into the tank at the rate of 3 L/min and brine solution runs out at the rate of 2 L/min. The solution is kept stirred to make the concentration uniform. Compute the kg of salt in the tank after 1.0 hour.Question 6Select one:A.13.59 kgB.19.35 kgC.19.53 kgD.15.93 kg

A tank is filled with 1000 liters of pure water. Brine containing 0.04 kg of salt per liter enters the tank at 6 liters per minute. Another brine solution containing 0.06 kg of salt per liter enters the tank at 6 liters per minute. The contents of the tank are kept thoroughly mixed and the drains from the tank at 12 liters per minute.A. Determine the differential equation which describes this system. Let 𝑆(𝑡) denote the number of kg of salt in the tank after 𝑡 minutes.

What is the solute in a salt solution like brine?

Measurements have shown that the concentration of salt in seawater is 35.5·gL−1. Calculate the volume in liters of seawater that must be evaporated to recover 0.0500kg of salt.Round your answer to 3 significant digits.
