- A patient's blood is traveling at a rate of 16 mL/sec while conveying a medicine into the liver and leaves in a similar rate. The liver can occupy liquid volume of 204 mL. The medicine concentration in the blood entering the liver is 0.5 g/mL, When will the concentration of the medicine in the liver reach 0.4 g/mL?A 100-gallon tank contains 50 gallons of water. Brine, containing 2 lbs of salt per gallon, flows into the tank at the rate of 2 gallons per minute, and the mixture, kept uniform by stirring, runs out at the rate of 1 gallon per minute. approximate the amount of salt in kilogram present when the tank is three-fourths full of brine solution.Triple Integral
