Hemodialysis is a process by which a machine is used to filter urea and other waste products from an individual's blood when the kidneys fail. Let c(t) be the concentration of urea in the blood after t minutes. We can model the concentration of urea as an exponential decay c(t) = coe v where 1. K is the mass transfer coefficient measured in ml/min 2. V is the blood Volume 3. co is the initial concentration of urea Suppose that a patient has a mass transfer value of K=340ml/min and a Blood Volume of V=32,941. How long should this patient be put on dialysis machine to reduce the concentration of urea from 1.65 mg/ml to . omg/ml
