Figure P4.1.4 is a sketch of an artificial kidney, a medica device used to remove waste metabolites from the blood in cases of kidney malfunction. The dialying fliud passes across a hollow membrane, and the waste products diffuse from the blood into the dialyzing fluid. If the blood entering the unit flows at the rate of 220 mL/ min and the blood existing the units flows at the rate of 215mL/ min, how much water and urea (the main waste product) pass into the dialysate if the entering concentration of urea is 2.30 mg/mL and the exit concentration of urea is 1.70mg/ mL? If the dialyzing fliud flows into the unit at the rate of 1500 mL/ min, what is the concentration of the urea in the dialysate?
