Calculate the flux and the rate of removal of urea at steady-state in g/h from blood in a cellophane membrane dialyzer at 37oc. membrane thickness is 0.025 mm thick and has an area of 2m2. the mass transfer coefficient on the blood side is estimated as kc1=1.25x10-5 m/s and on the aqueous side is 3.33x10-5m/s. the permeance of the membrane is 8.73x10-6 m/s. the concentration of urea in blood is 0.02 g urea/100ml and in the dialyzing fluid urea concentration is assumed to be 0.

Rate of removal of urea = 6.44 gram/hr

Explanation:

Given Data:

we know flux formula is given as

      =200 gram/m^3,

Rate of removal of urea

Rate of removal of urea = 6.44 gram/hr

in a word, a scientific question is testable. a testable question is one that asks about objects, organisms or events found in the world around it

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
