Counter-current flow through the artificial kidney is used so that the dialysate enters the kidney at the blood exit-end. Where the blood concentration of waste products is at the lowest level?

Counter-current flow through the artificial kidney is used so that the dialysate enters the kidney at the blood exit-end. Where the blood concentration of waste products is at the lowest level? Correct Answer lowest level

Counter-current flow through the artificial kidney is used so that the dialysate enters the kidney at the blood exit-end where blood concentration of waste products is at the lowest level. The removal of waste products during dialysis is proportional to the concentration gradient across the membrane. In order to effect the maximum gradient, the concentration of waste products in the dialysate should be maintained at zero.

The fasting blood sugar level (F) and the post prandial blood sugar level (PP) of a patient was monitored for four weeks W1, W2, W3, W4, and the readings (in mg/dl) for the four weeks are as follows: F/PP: 170/220, 150/180, 120/150, 90/120. These have been presented through a bar graph.

A kidney can be taken safely from a living person, and can save the life of a dying patient. Given that the demand for kidney transplants exceeds the supply of donated kidneys, the law in the India that forbids people to sell one of their kidneys should be abolished, because this would result in a greater number of successful kidney transplants. People are worried that it would involve rich patients exploiting poor potential donors. But selling one's kidney to support one's family is not very much different from supporting one's family by working in a dangerous occupation. Some patients have bought kidneys and received transplants in other countries, where the risks to their life from such operations can be great. Select an assumption supporting the above argument from following options.

A pollutant P degrades according to first order kinetics. An aqueous stream containing P at 2 kmole/m3 and volumetric flow rate 1 m3/h requires a mixed flow reactor of volume V to bring down the pollutant level to 0.5 kmole/m3. The inlet concentration of the pollutant is now doubled and the volumetric flow rate is tripled. If the pollutant level is to be brought down to the same level of 0.5 kmole/m3, the volume of the mixed flow reactor should be increased by a factor of
A company paid Rs. 6,00,000 as bonus to its employees at different levels A, B and C. Each employee at level A receives one and half times of the amount that was paid to each employee at level B and each employee at level B was paid twice the amount paid to the employee at level C. If 50 employees were on level A, 75 on level B and 100 on level C, how much amount was paid to each employee of level A ?
The concentration of oxygen at the inner surface of the vessel is maintained at a level C depending on the pressure in the vessel, while the concentration at the outer surface is reduced to zero by the escape of oxygen to the surroundings. A steady state will eventually be reached when the concentration everywhere reaches a constant value. Provided D is independent of concentration there will be a single concentration gradient in the wall and the thickness of the wall is L, the flux is given by________________
